+	  Each function can be configured and enabled/disabled
+	  dynamically from userspace through a sysfs interface.
+
+	  In order to compile this (either as a module or built-in),
+	  "USB Gadget Drivers" and anything under it must not be
+	  selected compiled-in in
+	  Device Drivers->USB Support->USB Gadget Support.
+	  However, you can say "M" there, if you do, the
+	  Configurable Composite Gadget can be compiled "M" only
+	  or not at all.

+
+    NAME
+        CsrLogLevelTextSet
+
+    DESCRIPTION
+        Set the text logging level for a given origin and optionally sub origin
+        by name. If either string is NULL or zero length, it is interpreted as
+        all origins and/or all sub origins respectively. If originName is NULL
+        or zero length, subOriginName is ignored.
+
+        Passing NULL or zero length strings in both originName and subOriginName
+        is equivalent to calling CsrLogLevelTextSetAll, and overrides all
+        previous filter configurations for all origins and sub origins.
+
+        Passing NULL or a zero length string in subOriginName overrides all
+        previous filter configurations for all sub origins of the specified
+        origin.
+
+        Note: the supplied strings may be accessed after the function returns
+        and must remain valid and constant until CsrLogDeinit is called.
+
+        Note: when specifying an origin (originName is not NULL and not zero
+        length), this function can only be used for origins that use the
+        csr_log_text_2.h interface for registration and logging. Filtering for
+        origins that use the legacy csr_log_text.h interface must be be
+        configured using the legacy filter configuration functions that accept
+        a CsrLogTextTaskId as origin specifier. However, when not specifying an
+        origin this function also affects origins that have been registered with
+        the legacy csr_log_text.h interface. Furthermore, using this function
+        and the legacy filter configuration functions on the same origin is not
+        allowed.
+
+    PARAMETERS
+        originName - a string containing the name of the origin. Can be NULL or
+            zero length to set the log level for all origins. In this case, the
+            subOriginName parameter will be ignored.
+        subOriginName - a string containing the name of the sub origin. Can be
+            NULL or zero length to set the log level for all sub origins of the
+            specified origin.
+        warningLevelMask - The desired log level for the specified origin(s) and
+            sub origin(s).

+ * - Function ----------------------------------------------------------------
+ * card_hw_init()
+ *
+ *      Perform the initialisation procedure described in the UniFi Host
+ *      Interface Protocol document (section 3.3.8) and read the run-time
+ *      configuration information from the UniFi. This is stuff like number
+ *      of bulk data slots etc.
+ *
+ *      The card enumeration and SD initialisation has already been done by
+ *      the SDIO library, see card_sdio_init().
+ *
+ *      The initialisation is done when firmware is ready, i.e. this may need
+ *      to be called after a f/w download operation.
+ *
+ *      The initialisation procedure goes like this:
+ *       - Wait for UniFi to start-up by polling SHARED_MAILBOX1
+ *       - Find the symbol table and look up SLT_SDIO_SLOT_CONFIG
+ *       - Read the config structure
+ *       - Check the "SDIO initialised" flag, if not zero do a h/w reset and
+ *         start again
+ *       - Decide the number of bulk data slots to allocate, allocate them and
+ *         set "SDIO initialised" flag (and generate an interrupt) to say so.
+ *
+ * Arguments:
+ *      card        Pointer to card struct
+ *
+ * Returns:
+ *      CSR_RESULT_SUCEESS on success,
+ *      a CSR error code on failure
+ *
+ * Notes:
+ *      All data in the f/w is stored in a little endian format, without any
+ *      padding bytes. Every read from this memory has to be transformed in
+ *      host (cpu specific) format, before it is stored in driver's parameters
+ *      or/and structures. Athough unifi_card_read16() and unifi_read32() do perform
+ *      the convertion internally, unifi_readn() does not.

+ * unreserved slots sufficient for this request. If available these slots are reserved for the queue.
+ * If there are not enough unreserved slots, a fair share for each queue is calculated based on the total slots

+ *  send_signal
+ *
+ *      This function queues a signal for sending to UniFi.  It first checks
+ *      that there is space on the fh_signal_queue for another entry, then
+ *      claims any bulk data slots required and copies data into them. Then
+ *      increments the fh_signal_queue write count.
+ *
+ *      The fh_signal_queue is later processed by the driver bottom half
+ *      (in unifi_bh()).
+ *
+ *      This function call unifi_pause_xmit() to pause the flow of data plane
+ *      packets when:
+ *        - the fh_signal_queue ring buffer is full
+ *        - there are less than UNIFI_MAX_DATA_REFERENCES (2) bulk data
+ *          slots available.
+ *
+ *  Arguments:
+ *      card            Pointer to card context structure
+ *      sigptr          Pointer to the signal to write to UniFi.
+ *      siglen          Number of bytes pointer to by sigptr.
+ *      bulkdata        Array of pointers to an associated bulk data.
+ *      sigq            To which from-host queue to add the signal.
+ *
+ *  Returns:
+ *      CSR_RESULT_SUCCESS on success
+ *      CSR_WIFI_HIP_RESULT_NO_SPACE if there were insufficient data slots or
+ *                              no free signal queue entry
+ *

+    The wireless manager application should call this primitive to notify the

+    allows the wireless manager application to query, add, remove, and flush
+    the BSSIDs that the driver may not connect or roam to.
+    When this primitive adds to the black list the BSSID to which the SME is
+    currently connected, the SME will try to roam, if applicable, to another
+    BSSID in the same ESS; if the roaming procedure fails, the SME will
+    disconnect.

+
+  NAME
+    CsrWifiSmeConnectReqSend
+
+  DESCRIPTION
+    The wireless manager application calls this primitive to start the
+    process of joining an 802.11 wireless network or to start an ad hoc
+    network.
+    The structure pointed by connectionConfig contains parameters describing
+    the network to join or, in case of an ad hoc network, to host or join.
+    The SME will select a network, perform the IEEE 802.11 Join, Authenticate
+    and Associate exchanges.
+    The SME selects the networks from the current scan list that match both
+    the SSID and BSSID, however either or both of these may be the wildcard
+    value. Using this rule, the following operations are possible:
+      * To connect to a network by name, specify the SSID and set the BSSID to
+        0xFF 0xFF 0xFF 0xFF 0xFF 0xFF. If there are two or more networks visible,
+        the SME will select the one with the strongest signal.
+      * To connect to a specific network, specify the BSSID. The SSID is
+        optional, but if given it must match the SSID of the network. An empty
+        SSID may be specified by setting the SSID length to zero. Please note
+        that if the BSSID is specified (i.e. not equal to 0xFF 0xFF 0xFF 0xFF
+        0xFF 0xFF), the SME will not attempt to roam if signal conditions become
+        poor, even if there is an alternative AP with an SSID that matches the
+        current network SSID.
+      * To connect to any network matching the other parameters (i.e. security,
+        etc), set the SSID length to zero and set the BSSID to 0xFF 0xFF 0xFF
+        0xFF 0xFF 0xFF. In this case, the SME will order all available networks
+        by their signal strengths and will iterate through this list until it
+        successfully connects.
+    NOTE: Specifying the BSSID will restrict the selection to one specific
+    network. If SSID and BSSID are given, they must both match the network
+    for it to be selected. To select a network based on the SSID only, the
+    wireless manager application must set the BSSID to 0xFF 0xFF 0xFF 0xFF
+    0xFF 0xFF.
+    The SME will try to connect to each network that matches the provided
+    parameters, one by one, until it succeeds or has tried unsuccessfully
+    with all the matching networks.
+    If there is no network that matches the parameters and the request allows
+    to host an ad hoc network, the SME will advertise a new ad hoc network
+    instead.
+    If the SME cannot connect, it will notify the failure in the confirm.
+

+
+  NAME
+    CsrWifiSmePacketFilterSetReqSend
+
+  DESCRIPTION
+    The wireless manager application should call this primitive to enable or
+    disable filtering of broadcast packets: uninteresting broadcast packets
+    will be dropped by the Wi-Fi chip, instead of passing them up to the
+    host.
+    This has the advantage of saving power in the host application processor
+    as it removes the need to process unwanted packets.
+    All broadcast packets are filtered according to the filter and the filter
+    mode provided, except ARP packets, which are filtered using
+    arpFilterAddress.
+    Filters are not cumulative: only the parameters specified in the most
+    recent successful request are significant.
+    For more information, see 'UniFi Firmware API Specification'.
+
+  PARAMETERS
+    queue            - Message Source Task Queue (Cfm's will be sent to this Queue)
+    interfaceTag     - Interface Identifier; unique identifier of an interface
+    filterLength     - Length of the filter in bytes.
+                       filterLength=0 disables the filter previously set
+    filter           - Points to the first byte of the filter provided, if any.
+                       This shall include zero or more instance of the
+                       information elements of one of these types
+                         * Traffic Classification (TCLAS) elements
+                         * WMM-SA TCLAS elements
+    mode             - Specifies whether the filter selects or excludes packets
+                       matching the filter
+    arpFilterAddress - IPv4 address to be used for filtering the ARP packets.
+                         * If the specified address is the IPv4 broadcast address
+                           (255.255.255.255), all ARP packets are reported to the
+                           host,
+                         * If the specified address is NOT the IPv4 broadcast
+                           address, only ARP packets with the specified address in
+                           the Source or Target Protocol Address fields are reported
+                           to the host

+  NAME
+    CsrWifiSmeRoamStartIndSend
+
+  DESCRIPTION
+    The SME will send this primitive to all the tasks that have registered to
+    receive it whenever it begins an attempt to roam to an AP.
+    If the wireless manager application connect request specified the SSID
+    and the BSSID was set to the broadcast address (0xFF 0xFF 0xFF 0xFF 0xFF
+    0xFF), the SME monitors the signal quality and maintains a list of
+    candidates to roam to. When the signal quality of the current connection
+    falls below a threshold, and there is a candidate with better quality,
+    the SME will attempt to the candidate AP.
+    If the roaming procedure succeeds, the SME will also issue a Media
+    Connect indication to inform the wireless manager application of the
+    change.
+    NOTE: to prevent the SME from initiating roaming the WMA must specify the
+    BSSID in the connection request; this forces the SME to connect only to
+    that AP.
+    The wireless manager application can obtain statistics for roaming
+    purposes using CSR_WIFI_SME_CONNECTION_QUALITY_IND and
+    CSR_WIFI_SME_CONNECTION_STATS_GET_REQ.
+    When the wireless manager application wishes to roam to another AP, it
+    must issue a connection request specifying the BSSID of the desired AP.

+
+  NAME
+    CsrWifiSmeTspecReqSend
+
+  DESCRIPTION
+    The wireless manager application should call this primitive to use the
+    TSPEC feature.
+    The chip supports the use of TSPECs and TCLAS for the use of IEEE
+    802.11/WMM Quality of Service features.
+    The API allows the wireless manager application to supply a correctly
+    formatted TSPEC and TCLAS pair to the driver.
+    After performing basic validation, the driver negotiates the installation
+    of the TSPEC with the AP as defined by the 802.11 specification.
+    The driver retains all TSPEC and TCLAS pairs until they are specifically
+    removed.
+    It is not compulsory for a TSPEC to have a TCLAS (NULL is used to
+    indicate that no TCLAS is supplied), while a TCLASS always require a
+    TSPEC.
+    The format of the TSPEC element is specified in 'WMM (including WMM Power
+    Save) Specification - Version 1.1' and 'ANSI/IEEE Std 802.11-REVmb/D3.0'.
+    For more information, see 'UniFi Configuring WMM and WMM-PS'.

+                    CSR_WIFI_SME_LIST_ACTION_FLUSH is not applicable here.
+    transactionId - Unique Transaction ID for the TSPEC, as assigned by the
+                    driver
+    strict        - If it set to false, allows the SME to perform automatic
+                    TSPEC negotiation

+
+  NAME
+    CsrWifiSmeWifiFlightmodeReqSend
+
+  DESCRIPTION
+    The wireless manager application may call this primitive on boot-up of
+    the platform to ensure that the chip is placed in a mode that prevents
+    any emission of RF energy.
+    This primitive is an alternative to CSR_WIFI_SME_WIFI_ON_REQ.
+    As in CSR_WIFI_SME_WIFI_ON_REQ, it causes the download of the patch file
+    (if any) and the programming of the initial MIB settings (if supplied by
+    the WMA), but it also ensures that the chip is left in its lowest
+    possible power-mode with the radio subsystems disabled.
+    This feature is useful on platforms where power cannot be removed from
+    the chip (leaving the chip not initialised will cause it to consume more
+    power so calling this function ensures that the chip is initialised into
+    a low power mode but without entering a state where it could emit any RF
+    energy).
+    NOTE: this primitive does not cause the Wi-Fi to change state: Wi-Fi
+    stays conceptually off. Configuration primitives can be sent after
+    CSR_WIFI_SME_WIFI_FLIGHTMODE_REQ and the configuration will be maintained.
+    Requests that require the state of the Wi-Fi to be ON will return
+    CSR_WIFI_SME_STATUS_WIFI_OFF in their confirms.
+
+  PARAMETERS
+    queue         - Message Source Task Queue (Cfm's will be sent to this Queue)
+    address       - Optionally specifies a station MAC address.
+                    In normal use, the manager should set the address to 0xFF
+                    0xFF 0xFF 0xFF 0xFF 0xFF, which will cause the chip to use
+                    the MAC address in the MIB.
+    mibFilesCount - Number of provided data blocks with initial MIB values
+    mibFiles      - Points to the first data block with initial MIB values.
+                    These data blocks are typically the contents of the provided
+                    files ufmib.dat and localmib.dat, available from the host
+                    file system, if they exist.
+                    These files typically contain radio tuning and calibration
+                    values.
+                    More values can be created using the Host Tools.

+
+  DESCRIPTION
+    The wireless manager application calls this primitive to start the
+    process of joining an 802.11 wireless network or to start an ad hoc
+    network.
+    The structure pointed by connectionConfig contains parameters describing
+    the network to join or, in case of an ad hoc network, to host or join.
+    The SME will select a network, perform the IEEE 802.11 Join, Authenticate
+    and Associate exchanges.
+    The SME selects the networks from the current scan list that match both
+    the SSID and BSSID, however either or both of these may be the wildcard
+    value. Using this rule, the following operations are possible:
+      * To connect to a network by name, specify the SSID and set the BSSID to
+        0xFF 0xFF 0xFF 0xFF 0xFF 0xFF. If there are two or more networks visible,
+        the SME will select the one with the strongest signal.
+      * To connect to a specific network, specify the BSSID. The SSID is
+        optional, but if given it must match the SSID of the network. An empty
+        SSID may be specified by setting the SSID length to zero. Please note
+        that if the BSSID is specified (i.e. not equal to 0xFF 0xFF 0xFF 0xFF
+        0xFF 0xFF), the SME will not attempt to roam if signal conditions become
+        poor, even if there is an alternative AP with an SSID that matches the
+        current network SSID.
+      * To connect to any network matching the other parameters (i.e. security,
+        etc), set the SSID length to zero and set the BSSID to 0xFF 0xFF 0xFF
+        0xFF 0xFF 0xFF. In this case, the SME will order all available networks
+        by their signal strengths and will iterate through this list until it
+        successfully connects.
+    NOTE: Specifying the BSSID will restrict the selection to one specific
+    network. If SSID and BSSID are given, they must both match the network
+    for it to be selected. To select a network based on the SSID only, the
+    wireless manager application must set the BSSID to 0xFF 0xFF 0xFF 0xFF
+    0xFF 0xFF.
+    The SME will try to connect to each network that matches the provided
+    parameters, one by one, until it succeeds or has tried unsuccessfully
+    with all the matching networks.
+    If there is no network that matches the parameters and the request allows
+    to host an ad hoc network, the SME will advertise a new ad hoc network
+    instead.
+    If the SME cannot connect, it will notify the failure in the confirm.

+    The wireless manager application may call this primitive on boot-up of

+    any emission of RF energy.
+    This primitive is an alternative to CSR_WIFI_SME_WIFI_ON_REQ.
+    As in CSR_WIFI_SME_WIFI_ON_REQ, it causes the download of the patch file
+    (if any) and the programming of the initial MIB settings (if supplied by
+    the WMA), but it also ensures that the chip is left in its lowest
+    possible power-mode with the radio subsystems disabled.
+    This feature is useful on platforms where power cannot be removed from
+    the chip (leaving the chip not initialised will cause it to consume more
+    power so calling this function ensures that the chip is initialised into
+    a low power mode but without entering a state where it could emit any RF
+    energy).
+    NOTE: this primitive does not cause the Wi-Fi to change state: Wi-Fi
+    stays conceptually off. Configuration primitives can be sent after
+    CSR_WIFI_SME_WIFI_FLIGHTMODE_REQ and the configuration will be maintained.

+    If the roaming procedure succeeds, the SME will also issue a Media
+    Connect indication to inform the wireless manager application of the
+    change.
+    NOTE: to prevent the SME from initiating roaming the WMA must specify the

+ *
+ * When the unifi_sdio.ko modules loads, the linux kernel calls unifi_load().
+ * unifi_load() calls uf_sdio_load() which is exported by the SDIO glue
+ * layer. uf_sdio_load() registers this driver with the underlying SDIO driver.
+ * When a card is detected, the SDIO glue layer calls register_unifi_sdio()
+ * to pass the SDIO function context and ask the OS layer to initialise
+ * the card. register_unifi_sdio() allocates all the private data of the OS
+ * layer and calls uf_run_unifihelper() to start the SME. The SME calls
+ * unifi_sys_wifi_on_req() which uses the HIP core lib to initialise the card.

+ *
+ *  PURPOSE:
+ *      This file contains routines that the SDIO driver can call when a
+ *      UniFi card is first inserted (or detected) and removed.
+ *
+ *      When used with sdioemb, the udev scripts (at least on Ubuntu) don't
+ *      recognise a UniFi being added to the system. This is because sdioemb
+ *      does not register itself as a device_driver, it uses it's own code
+ *      to handle insert and remove.
+ *      To have Ubuntu recognise UniFi, edit /etc/udev/rules.d/85-ifupdown.rules
+ *      to change this line:
+ *          SUBSYSTEM=="net", DRIVERS=="?*", GOTO="net_start"
+ *      to these:
+ *          #SUBSYSTEM=="net", DRIVERS=="?*", GOTO="net_start"
+ *          SUBSYSTEM=="net", GOTO="net_start"
+ *
+ *      Then you can add a stanza to /etc/network/interfaces like this:
+ *          auto eth1
+ *          iface eth1 inet dhcp
+ *          wpa-conf /etc/wpa_supplicant.conf
+ *      This will then automatically associate when a car dis inserted.

+ *
+ * Notes:
+ *      This function waits for a specific (sig_reply_id) signal from UniFi.
+ *      It also match the sequence number of the received (cfm) signal, with
+ *      the latest sequence number of the signal (req) we have sent.
+ *      These two number match be equal.
+ *      Should only be used for waiting xxx.cfm signals and only after
+ *      we have sent the matching xxx.req signal to UniFi.
+ *      If no response is received within the expected time (timeout), we assume
+ *      that the UniFi is busy and return an error.
+ *      If the wait is aborted by a kernel signal arriving, we stop waiting.
+ *      If a response from UniFi is not what we expected, we discard it and
+ *      wait again. This could be a response from an aborted request. If we

+/*
+ * Porting Notes:
+ * This file implements the data plane of the UniFi linux driver.
+ *
+ * All the Tx packets are passed to the HIP core lib, using the
+ * unifi_send_signal() API. For EAPOL packets use the MLME-EAPOL.req
+ * signal, for all other use the MLME-UNITDATA.req. The unifi_send_signal()
+ * expects the wire-formatted (packed) signal. For convenience, in the OS
+ * layer we only use the native (unpacked) signal structures. The HIP core lib
+ * provides the write_pack() helper function to convert to the packed signal.
+ * The packet is stored in the bulk data of the signal. We do not need to
+ * allocate new memory to store the packet, because unifi_net_data_malloc()
+ * is implemented to return a skb, which is the format of packet in Linux.
+ * The HIP core lib frees the bulk data buffers, so we do not need to do
+ * this in the OS layer.
+ *
+ * All the Rx packets are MLME-UNITDATA.ind signals, passed by the HIP core lib
+ * in unifi_receive_event(). We do not need to allocate an skb and copy the
+ * received packet because the HIP core lib has stored in memory allocated by
+ * unifi_net_data_malloc(). Also, we can perform the 802.11 to Ethernet
+ * translation in-place because we allocate the extra memory allocated in
+ * unifi_net_data_malloc().
+ *
+ * If possible, the porting exercise should appropriately implement
+ * unifi_net_data_malloc() and unifi_net_data_free() to save copies between
+ * network and driver buffers.

+ * In order to support QoS in these kernels, multiple queues are implemented in the driver. But since
+ * there is only a single queue in the kernel (leading to multiple queues in the driver) there is no possibility
+ * of stopping a particular queue in the kernel. Stopping the single kernel queue leads to undesirable starvation
+ * of driver queues. One of the proposals is to not stop the kernel queue but to prevent dequeuing from the
+ * 'stopped' driver queue. Allow q pause is an experimental implementation of this scheme for pre 2.6.28 kernels.
+ * When NOT defined, queues are paused locally in the driver and packets are dequeued for transmission only from the
+ * unpaused queues. When Allow q pause is defined the kernel queue is stopped whenever any driver queue is paused.

+ * This file also contains the implementation of the asyncronous
+ * requests to the SME.
+ *
+ * Before calling an asyncronous SME function, we call sme_init_request()
+ * which gets hold of the SME semaphore and updates the request status.
+ * The semaphore makes sure that there is only one pending request to
+ * the SME at a time.
+ *
+ * Now we are ready to call the SME function, but only if
+ * sme_init_request() has returned 0.
+ *
+ * When the SME function returns, we need to wait
+ * for the reply. This is done in sme_wait_for_reply().
+ * If the request times-out, the request status is set to SME_REQUEST_TIMEDOUT
+ * and the sme_wait_for_reply() returns.
+ *
+ * If the SME replies in time, we call sme_complete_request().
+ * There we change the request status to SME_REQUEST_RECEIVED. This will
+ * wake up the process waiting on sme_wait_for_reply().
+ * It is important that we copy the reply data in priv->sme_reply
+ * before calling sme_complete_request().
+ *
+ * Handling the wext requests, we need to block
+ * until the SME sends the response to our request.
+ * We use the sme_init_request() and sme_wait_for_reply()
+ * to implement this behavior in the following functions:
+ * sme_mgt_wifi_on()
+ * sme_mgt_wifi_off()
+ * sme_mgt_scan_full()

-Description:
-		Some devices have internal clocks.  This parameter sets the
-		resulting sampling frequency.  In many devices this
-		parameter has an effect on input filters etc rather than
-		simply controlling when the input is sampled.  As this
-		effects datardy triggers, hardware buffers and the sysfs
-		direct access interfaces, it may be found in any of the
-		relevant directories.  If it effects all of the above
-		then it is to be found in the base device directory.

-Description:
-		Specifies the value of rate of change threshold that the
-		device is comparing against for the events enabled by
-		<type>[Y][_name]_roc[_rising|falling]_en.
-		If separate attributes exist for the two directions,
-		but direction is not specified for this attribute,
-		then a single threshold value applies to both directions.
-		The raw or input element of the name indicates whether the
-		value is in raw device units or in processed units (as _raw
-		and _input do on sysfs direct channel read attributes).

-Description:
-		Description of the scan element data storage within the buffer
-		and hence the form in which it is read from user-space.
-		Form is [be|le]:[s|u]bits/storagebits[>>shift].
-		be or le specifies big or little endian. s or u specifies if
-		signed (2's complement) or unsigned. bits is the number of bits
-		of data and storagebits is the space (after padding) that it
-		occupies in the buffer. shift if specified, is the shift that
-		needs to be applied prior to masking out unused bits. Some
-		devices put their data in the middle of the transferred elements
-		with additional information on both sides.  Note that some
-		devices will have additional information in the unused bits
-		so to get a clean value, the bits value must be used to mask
-		the buffer output value appropriately.  The storagebits value
-		also specifies the data alignment.  So s48/64>>2 will be a
-		signed 48 bit integer stored in a 64 bit location aligned to
-		a a64 bit boundary. To obtain the clean value, shift right 2
-		and apply a mask to zero the top 16 bits of the result.
-		For other storage combinations this attribute will be extended
-		appropriately.

-		Hardware or software applied calibration scale factor assumed
-		to account for attenuation due to industrial design (glass
-		filters or aperture holes).
+		This property gets/sets the table of coefficients
+		used in calculating illuminance in lux.

+Description:
+		This property is supported by sensors that have a RGBC
+		sensing mode. This value should be the output from a reading
+		and if expressed in SI units, should include _input. If this
+		value is not in SI units (irradiance, uW/mm^2), then it should
+		include _raw.

+Contact:	linux-iio@vger.kernel.org
+Description:
+		This should return the correlated color temperature from the
+		light sensor. If it comes back in SI units, it should also
+		include _input else it should include _raw to signify it is not
+		in SI units.

- * @address:		Driver specific identifier.
- * @scan_index:	Monotonic index to give ordering in scans when read
- *			from a buffer.
- * @scan_type:		Sign:		's' or 'u' to specify signed or unsigned
- *			realbits:	Number of valid bits of data
- *			storage_bits:	Realbits + padding
- *			shift:		Shift right by this before masking out
- *					realbits.
- *			endianness:	little or big endian
- * @info_mask:		What information is to be exported about this channel.
- *			This includes calibbias, scale etc.
- * @event_mask:	What events can this channel produce.
- * @ext_info:		Array of extended info attributes for this channel.
- *			The array is NULL terminated, the last element should
- *			have it's name field set to NULL.
- * @extend_name:	Allows labeling of channel attributes with an
- *			informative name. Note this has no effect codes etc,
- *			unlike modifiers.
- * @datasheet_name:	A name used in in kernel mapping of channels. It should
- *			correspond to the first name that the channel is referred
- *			to by in the datasheet (e.g. IND), or the nearest
- *			possible compound name (e.g. IND-INC).
- * @processed_val:	Flag to specify the data access attribute should be
- *			*_input rather than *_raw.
- * @modified:		Does a modifier apply to this channel. What these are
- *			depends on the channel type.  Modifier is set in
- *			channel2. Examples are IIO_MOD_X for axial sensors about
- *			the 'x' axis.
- * @indexed:		Specify the channel has a numerical index. If not,
- *			the value in channel will be suppressed for attribute
- *			but not for event codes. Typically set it to 0 when
- *			the index is false.
- * @differential:	Channel is differential.

+				TODO
+				====
+Introduction
+============
+
+These drivers add support for IndustryPack devices: carrier and IP module
+boards.
+
+The ipack driver is just an abstraction of the bus providing the common
+operations between the two kind of boards.
+
+TODO
+====
+
+TPCI-200
+--------
+
+* It has a linked list with the tpci200 devices it is managing. Get rid of it
+  and use driver_for_each_device() instead.
+
+IP-OCTAL
+--------
+
+* It has a linked list which saves the devices it is currently
+  managing. It should use the driver_for_each_device() function. It is not there
+  due to the impossibility of using container_of macro to recover the
+  corresponding "struct ipoctal" because the attribute "struct ipack_device" is
+  a pointer. This code should be refactored.
+
+Ipack
+-----
+
+* The structures and API exported can be improved a lot. For example, the
+  way to unregistering IP module devices, doing the IP module driver a call to
+  remove_device() to notify the carrier driver, or the opposite with the call to
+  the ipack_driver_ops' remove() function could be improved.

-Introduction
-=======================
-
-The Intel Management Engine (Intel ME) is an isolated and protected computing
-resource (Co-processor) residing inside certain Intel chipsets. The Intel ME
-provides support for computer/IT management features. The feature set
-depends on the Intel chipset SKU.
-
-The Intel Management Engine Interface (Intel MEI, previously known as HECI)
-is the interface between the Host and Intel ME. This interface is exposed
-to the host as a PCI device. The Intel MEI Driver is in charge of the
-communication channel between a host application and the Intel ME feature.
-
-Each Intel ME feature (Intel ME Client) is addressed by a GUID/UUID and
-each client has its own protocol. The protocol is message-based with a
-header and payload up to 512 bytes.
-
-Prominent usage of the Intel ME Interface is to communicate with Intel(R)
-Active Management Technology (Intel AMT)implemented in firmware running on
-the Intel ME.
-
-Intel AMT provides the ability to manage a host remotely out-of-band (OOB)
-even when the operating system running on the host processor has crashed or
-is in a sleep state.
-
-Some examples of Intel AMT usage are:
-   - Monitoring hardware state and platform components
-   - Remote power off/on (useful for green computing or overnight IT
-     maintenance)
-   - OS updates
-   - Storage of useful platform information such as software assets
-   - Built-in hardware KVM
-   - Selective network isolation of Ethernet and IP protocol flows based
-     on policies set by a remote management console
-   - IDE device redirection from remote management console
-
-Intel AMT (OOB) communication is based on SOAP (deprecated
-starting with Release 6.0) over HTTP/S or WS-Management protocol over
-HTTP/S that are received from a remote management console application.
-
-For more information about Intel AMT:
-http://software.intel.com/sites/manageability/AMT_Implementation_and_Reference_Guide
-
-Intel MEI Driver
-=======================
-
-The driver exposes a misc device called /dev/mei.
-
-An application maintains communication with an Intel ME feature while
-/dev/mei is open. The binding to a specific features is performed by calling
-MEI_CONNECT_CLIENT_IOCTL, which passes the desired UUID.
-The number of instances of an Intel ME feature that can be opened
-at the same time depends on the Intel ME feature, but most of the
-features allow only a single instance.
-
-The Intel AMT Host Interface (Intel AMTHI) feature supports multiple
-simultaneous user applications. Therefore, the Intel MEI driver handles
-this internally by maintaining request queues for the applications.
-
-The driver is oblivious to data that is passed between firmware feature
-and host application.
-
-Because some of the Intel ME features can change the system
-configuration, the driver by default allows only a privileged
-user to access it.
-
-A code snippet for an application communicating with
-Intel AMTHI client:
-	struct mei_connect_client_data data;
-	fd = open(MEI_DEVICE);
-
-	data.d.in_client_uuid = AMTHI_UUID;
-
-	ioctl(fd, IOCTL_MEI_CONNECT_CLIENT, &data);
-
-	printf("Ver=%d, MaxLen=%ld\n",
-			data.d.in_client_uuid.protocol_version,
-			data.d.in_client_uuid.max_msg_length);
-
-	[...]
-
-	write(fd, amthi_req_data, amthi_req_data_len);
-
-	[...]
-
-	read(fd, &amthi_res_data, amthi_res_data_len);
-
-	[...]
-	close(fd);
-
-IOCTL:
-======
-The Intel MEI Driver supports the following IOCTL command:
-	IOCTL_MEI_CONNECT_CLIENT	Connect to firmware Feature (client).
-
-	usage:
-		struct mei_connect_client_data clientData;
-		ioctl(fd, IOCTL_MEI_CONNECT_CLIENT, &clientData);
-
-	inputs:
-		mei_connect_client_data struct contain the following
-		input field:
-
-		in_client_uuid -	UUID of the FW Feature that needs
-					to connect to.
-	outputs:
-		out_client_properties - Client Properties: MTU and Protocol Version.
-
-	error returns:
-		EINVAL	Wrong IOCTL Number
-		ENODEV	Device or Connection is not initialized or ready.
-			(e.g. Wrong UUID)
-		ENOMEM	Unable to allocate memory to client internal data.
-		EFAULT	Fatal Error (e.g. Unable to access user input data)
-		EBUSY	Connection Already Open
-
-	Notes:
-        max_msg_length (MTU) in client properties describes the maximum
-        data that can be sent or received. (e.g. if MTU=2K, can send
-        requests up to bytes 2k and received responses upto 2k bytes).
-
-Intel ME Applications:
-==============
-
-1) Intel Local Management Service (Intel LMS)
-
-	Applications running locally on the platform communicate with Intel AMT Release
-	2.0 and later releases in the same way that network applications do via SOAP
-	over HTTP (deprecated starting with Release 6.0) or with WS-Management over
-	SOAP over HTTP. This means that some Intel AMT features can be accessed from a
-	local application using the same network interface as a remote application
-	communicating with Intel AMT over the network.
-
-	When a local application sends a message addressed to the local Intel AMT host
-	name, the Intel LMS, which listens for traffic directed to the host name,
-	intercepts the message and routes it to the Intel MEI.
-	For more information:
-	http://software.intel.com/sites/manageability/AMT_Implementation_and_Reference_Guide
-	Under "About Intel AMT" => "Local Access"
-
-	For downloading Intel LMS:
-	http://software.intel.com/en-us/articles/download-the-latest-intel-amt-open-source-drivers/
-
-	The Intel LMS opens a connection using the Intel MEI driver to the Intel LMS
-	firmware feature using a defined UUID and then communicates with the feature
-	using a protocol called Intel AMT Port Forwarding Protocol(Intel APF protocol).
-	The protocol is used to maintain multiple sessions with Intel AMT from a
-	single application.
-
-	See the protocol specification in the Intel AMT Software Development Kit(SDK)
-	http://software.intel.com/sites/manageability/AMT_Implementation_and_Reference_Guide
-	Under "SDK Resources" => "Intel(R) vPro(TM) Gateway(MPS)"
-	=> "Information for Intel(R) vPro(TM) Gateway Developers"
-	=> "Description of the Intel AMT Port Forwarding (APF)Protocol"
-
-  2) Intel AMT Remote configuration using a Local Agent
-	A Local Agent enables IT personnel to configure Intel AMT out-of-the-box
-	without requiring installing additional data to enable setup. The remote
-	configuration process may involve an ISV-developed remote configuration
-	agent that runs on the host.
-	For more information:
-	http://software.intel.com/sites/manageability/AMT_Implementation_and_Reference_Guide
-	Under "Setup and Configuration of Intel AMT" =>
-	"SDK Tools Supporting Setup and Configuration" =>
-	"Using the Local Agent Sample"
-
-	An open source Intel AMT configuration utility,	implementing a local agent
-	that accesses the Intel MEI driver, can be found here:
-	http://software.intel.com/en-us/articles/download-the-latest-intel-amt-open-source-drivers/
-
-
-Intel AMT OS Health Watchdog:
-=============================
-The Intel AMT Watchdog is an OS Health (Hang/Crash) watchdog.
-Whenever the OS hangs or crashes, Intel AMT will send an event
-to any subscriber to this event. This mechanism means that
-IT knows when a platform crashes even when there is a hard failure on the host.
-
-The Intel AMT Watchdog is composed of two parts:
-	1) Firmware feature - receives the heartbeats
-	   and sends an event when the heartbeats stop.
-	2) Intel MEI driver - connects to the watchdog feature, configures the
-	   watchdog and sends the heartbeats.
-
-The Intel MEI driver uses the kernel watchdog to configure the Intel AMT
-Watchdog and to send heartbeats to it. The default timeout of the
-watchdog is 120 seconds.
-
-If the Intel AMT Watchdog feature does not exist (i.e. the connection failed),
-the Intel MEI driver will disable the sending of heartbeats.

+ *
+ * Revision 0.3.0.0 1999/11/16 daniela
+ * X.25 support.

+ * of the next-descr. and DMA buffer pointers on the DMA descriptors.
+ * Kernel buffer release and tbusy clearing is now done in the interrupt 
+ * handler.
+ * Fixed bug in cpc_open that would cause an interface reopen to fail.
+ * Added a protocol-specific code section in cpc_net_rx.
+ * Removed printk level defs (they might be added back after the beta phase).
+ *
+ * Revision 0.2.0.0 1999/10/28 ivan
+ * Revisited the code so that new protocols can be easily added / supported. 
+ *

+* Texas Instrument OMAP SCM bandgap bindings
+
+In the System Control Module, OMAP supplies a voltage reference
+and a temperature sensor feature that are gathered in the band
+gap voltage and temperature sensor (VBGAPTS) module. The band
+gap provides current and voltage reference for its internal
+circuits and other analog IP blocks. The analog-to-digital
+converter (ADC) produces an output value that is proportional
+to the silicon temperature.
+
+Required properties:
+- compatible : Should be:
+  - "ti,omap4460-control-bandgap" : for OMAP4460 bandgap
+  - "ti,omap5430-control-bandgap" : for OMAP5430 bandgap
+- interrupts : this entry should indicate which interrupt line
+the talert signal is routed to;
+Specific:
+- ti,tshut-gpio : this entry should be used to inform which GPIO
+line the tshut signal is routed to;
+
+Example:
+
+bandgap {
+	reg = <0x4a002260 0x4
+		0x4a00232C 0x4
+		0x4a002378 0x18>;
+	compatible = "ti,omap4460-control-bandgap";
+	interrupts = <0 126 4>; /* talert */
+	ti,tshut-gpio = <86>;
+};

-	  ESU-100 (which uses the serqt driver) even though it is an ESU2-100.
-	  Check the label on the bottom of your device.
-
-	  To compile this driver as a module, choose M here: the module will be

- *    after some grep or the sources...
- *   = Linus might want to rename all these macros and files to fit his taste,

- *   = cpu_to_beXX and beXX_to_cpu might some day need to be well

-			VME Device Driver API
-			=====================
-
-Driver registration
-===================
-
-As with other subsystems within the Linux kernel, VME device drivers register
-with the VME subsystem, typically called from the devices init routine.  This is
-achieved via a call to the following function:
-
-	int vme_register_driver (struct vme_driver *driver);
-
-If driver registration is successful this function returns zero, if an error
-occurred a negative error code will be returned.
-
-A pointer to a structure of type 'vme_driver' must be provided to the
-registration function. The structure is as follows:
-
-	struct vme_driver {
-		struct list_head node;
-		const char *name;
-		int (*match)(struct vme_dev *);
-		int (*probe)(struct vme_dev *);
-		int (*remove)(struct vme_dev *);
-		void (*shutdown)(void);
-		struct device_driver driver;
-		struct list_head devices;
-		unsigned int ndev;
-	};
-
-At the minimum, the '.name', '.match' and '.probe' elements of this structure
-should be correctly set. The '.name' element is a pointer to a string holding
-the device driver's name.
-
-The '.match' function allows controlling the number of devices that need to
-be registered. The match function should return 1 if a device should be
-probed and 0 otherwise. This example match function (from vme_user.c) limits
-the number of devices probed to one:
-
-	#define USER_BUS_MAX	1
-	...
-	static int vme_user_match(struct vme_dev *vdev)
-	{
-		if (vdev->id.num >= USER_BUS_MAX)
-			return 0;
-		return 1;
-	}
-
-The '.probe' element should contain a pointer to the probe routine. The
-probe routine is passed a 'struct vme_dev' pointer as an argument. The
-'struct vme_dev' structure looks like the following:
-
-	struct vme_dev {
-		int num;
-		struct vme_bridge *bridge;
-		struct device dev;
-		struct list_head drv_list;
-		struct list_head bridge_list;
-	};
-
-Here, the 'num' field refers to the sequential device ID for this specific
-driver. The bridge number (or bus number) can be accessed using
-dev->bridge->num.
-
-A function is also provided to unregister the driver from the VME core and is
-usually called from the device driver's exit routine:
-
-	void vme_unregister_driver (struct vme_driver *driver);
-
-
-Resource management
-===================
-
-Once a driver has registered with the VME core the provided match routine will
-be called the number of times specified during the registration. If a match
-succeeds, a non-zero value should be returned. A zero return value indicates
-failure. For all successful matches, the probe routine of the corresponding
-driver is called. The probe routine is passed a pointer to the devices
-device structure. This pointer should be saved, it will be required for
-requesting VME resources.
-
-The driver can request ownership of one or more master windows, slave windows
-and/or dma channels. Rather than allowing the device driver to request a
-specific window or DMA channel (which may be used by a different driver) this
-driver allows a resource to be assigned based on the required attributes of the
-driver in question:
-
-	struct vme_resource * vme_master_request(struct vme_dev *dev,
-		u32 aspace, u32 cycle, u32 width);
-
-	struct vme_resource * vme_slave_request(struct vme_dev *dev, u32 aspace,
-		u32 cycle);
-
-	struct vme_resource *vme_dma_request(struct vme_dev *dev, u32 route);
-
-For slave windows these attributes are split into the VME address spaces that
-need to be accessed in 'aspace' and VME bus cycle types required in 'cycle'.
-Master windows add a further set of attributes in 'width' specifying the
-required data transfer widths. These attributes are defined as bitmasks and as
-such any combination of the attributes can be requested for a single window,
-the core will assign a window that meets the requirements, returning a pointer
-of type vme_resource that should be used to identify the allocated resource
-when it is used. For DMA controllers, the request function requires the
-potential direction of any transfers to be provided in the route attributes.
-This is typically VME-to-MEM and/or MEM-to-VME, though some hardware can
-support VME-to-VME and MEM-to-MEM transfers as well as test pattern generation.
-If an unallocated window fitting the requirements can not be found a NULL
-pointer will be returned.
-
-Functions are also provided to free window allocations once they are no longer
-required. These functions should be passed the pointer to the resource provided
-during resource allocation:
-
-	void vme_master_free(struct vme_resource *res);
-
-	void vme_slave_free(struct vme_resource *res);
-
-	void vme_dma_free(struct vme_resource *res);
-
-
-Master windows
-==============
-
-Master windows provide access from the local processor[s] out onto the VME bus.
-The number of windows available and the available access modes is dependent on
-the underlying chipset. A window must be configured before it can be used.
-
-
-Master window configuration
----------------------------
-
-Once a master window has been assigned the following functions can be used to
-configure it and retrieve the current settings:
-
-	int vme_master_set (struct vme_resource *res, int enabled,
-		unsigned long long base, unsigned long long size, u32 aspace,
-		u32 cycle, u32 width);
-
-	int vme_master_get (struct vme_resource *res, int *enabled,
-		unsigned long long *base, unsigned long long *size, u32 *aspace,
-		u32 *cycle, u32 *width);
-
-The address spaces, transfer widths and cycle types are the same as described
-under resource management, however some of the options are mutually exclusive.
-For example, only one address space may be specified.
-
-These functions return 0 on success or an error code should the call fail.
-
-
-Master window access
---------------------
-
-The following functions can be used to read from and write to configured master
-windows. These functions return the number of bytes copied:
-
-	ssize_t vme_master_read(struct vme_resource *res, void *buf,
-		size_t count, loff_t offset);
-
-	ssize_t vme_master_write(struct vme_resource *res, void *buf,
-		size_t count, loff_t offset);
-
-In addition to simple reads and writes, a function is provided to do a
-read-modify-write transaction. This function returns the original value of the
-VME bus location :
-
-	unsigned int vme_master_rmw (struct vme_resource *res,
-		unsigned int mask, unsigned int compare, unsigned int swap,
-		loff_t offset);
-
-This functions by reading the offset, applying the mask. If the bits selected in
-the mask match with the values of the corresponding bits in the compare field,
-the value of swap is written the specified offset.
-
-
-Slave windows
-=============
-
-Slave windows provide devices on the VME bus access into mapped portions of the
-local memory. The number of windows available and the access modes that can be
-used is dependent on the underlying chipset. A window must be configured before
-it can be used.
-
-
-Slave window configuration
---------------------------
-
-Once a slave window has been assigned the following functions can be used to
-configure it and retrieve the current settings:
-
-	int vme_slave_set (struct vme_resource *res, int enabled,
-		unsigned long long base, unsigned long long size,
-		dma_addr_t mem, u32 aspace, u32 cycle);
-
-	int vme_slave_get (struct vme_resource *res, int *enabled,
-		unsigned long long *base, unsigned long long *size,
-		dma_addr_t *mem, u32 *aspace, u32 *cycle);
-
-The address spaces, transfer widths and cycle types are the same as described
-under resource management, however some of the options are mutually exclusive.
-For example, only one address space may be specified.
-
-These functions return 0 on success or an error code should the call fail.
-
-
-Slave window buffer allocation
-------------------------------
-
-Functions are provided to allow the user to allocate and free a contiguous
-buffers which will be accessible by the VME bridge. These functions do not have
-to be used, other methods can be used to allocate a buffer, though care must be
-taken to ensure that they are contiguous and accessible by the VME bridge:
-
-	void * vme_alloc_consistent(struct vme_resource *res, size_t size,
-		dma_addr_t *mem);
-
-	void vme_free_consistent(struct vme_resource *res, size_t size,
-		void *virt,	dma_addr_t mem);
-
-
-Slave window access
--------------------
-
-Slave windows map local memory onto the VME bus, the standard methods for
-accessing memory should be used.
-
-
-DMA channels
-============
-
-The VME DMA transfer provides the ability to run link-list DMA transfers. The
-API introduces the concept of DMA lists. Each DMA list is a link-list which can
-be passed to a DMA controller. Multiple lists can be created, extended,
-executed, reused and destroyed.
-
-
-List Management
----------------
-
-The following functions are provided to create and destroy DMA lists. Execution
-of a list will not automatically destroy the list, thus enabling a list to be
-reused for repetitive tasks:
-
-	struct vme_dma_list *vme_new_dma_list(struct vme_resource *res);
-
-	int vme_dma_list_free(struct vme_dma_list *list);
-
-
-List Population
----------------
-
-An item can be added to a list using the following function ( the source and
-destination attributes need to be created before calling this function, this is
-covered under "Transfer Attributes"):
-
-	int vme_dma_list_add(struct vme_dma_list *list,
-		struct vme_dma_attr *src, struct vme_dma_attr *dest,
-		size_t count);
-
-NOTE:	The detailed attributes of the transfers source and destination
-	are not checked until an entry is added to a DMA list, the request
-	for a DMA channel purely checks the directions in which the
-	controller is expected to transfer data. As a result it is
-	possible for this call to return an error, for example if the
-	source or destination is in an unsupported VME address space.
-
-Transfer Attributes
--------------------
-
-The attributes for the source and destination are handled separately from adding
-an item to a list. This is due to the diverse attributes required for each type
-of source and destination. There are functions to create attributes for PCI, VME
-and pattern sources and destinations (where appropriate):
-
-Pattern source:
-
-	struct vme_dma_attr *vme_dma_pattern_attribute(u32 pattern, u32 type);
-
-PCI source or destination:
-
-	struct vme_dma_attr *vme_dma_pci_attribute(dma_addr_t mem);
-
-VME source or destination:
-
-	struct vme_dma_attr *vme_dma_vme_attribute(unsigned long long base,
-		u32 aspace, u32 cycle, u32 width);
-
-The following function should be used to free an attribute:
-
-	void vme_dma_free_attribute(struct vme_dma_attr *attr);
-
-
-List Execution
---------------
-
-The following function queues a list for execution. The function will return
-once the list has been executed:
-
-	int vme_dma_list_exec(struct vme_dma_list *list);
-
-
-Interrupts
-==========
-
-The VME API provides functions to attach and detach callbacks to specific VME
-level and status ID combinations and for the generation of VME interrupts with
-specific VME level and status IDs.
-
-
-Attaching Interrupt Handlers
-----------------------------
-
-The following functions can be used to attach and free a specific VME level and
-status ID combination. Any given combination can only be assigned a single
-callback function. A void pointer parameter is provided, the value of which is
-passed to the callback function, the use of this pointer is user undefined:
-
-	int vme_irq_request(struct vme_dev *dev, int level, int statid,
-		void (*callback)(int, int, void *), void *priv);
-
-	void vme_irq_free(struct vme_dev *dev, int level, int statid);
-
-The callback parameters are as follows. Care must be taken in writing a callback
-function, callback functions run in interrupt context:
-
-	void callback(int level, int statid, void *priv);
-
-
-Interrupt Generation
---------------------
-
-The following function can be used to generate a VME interrupt at a given VME
-level and VME status ID:
-
-	int vme_irq_generate(struct vme_dev *dev, int level, int statid);
-
-
-Location monitors
-=================
-
-The VME API provides the following functionality to configure the location
-monitor.
-
-
-Location Monitor Management
----------------------------
-
-The following functions are provided to request the use of a block of location
-monitors and to free them after they are no longer required:
-
-	struct vme_resource * vme_lm_request(struct vme_dev *dev);
-
-	void vme_lm_free(struct vme_resource * res);
-
-Each block may provide a number of location monitors, monitoring adjacent
-locations. The following function can be used to determine how many locations
-are provided:
-
-	int vme_lm_count(struct vme_resource * res);
-
-
-Location Monitor Configuration
-------------------------------
-
-Once a bank of location monitors has been allocated, the following functions
-are provided to configure the location and mode of the location monitor:
-
-	int vme_lm_set(struct vme_resource *res, unsigned long long base,
-		u32 aspace, u32 cycle);
-
-	int vme_lm_get(struct vme_resource *res, unsigned long long *base,
-		u32 *aspace, u32 *cycle);
-
-
-Location Monitor Use
---------------------
-
-The following functions allow a callback to be attached and detached from each
-location monitor location. Each location monitor can monitor a number of
-adjacent locations:
-
-	int vme_lm_attach(struct vme_resource *res, int num,
-		void (*callback)(int));
-
-	int vme_lm_detach(struct vme_resource *res, int num);
-
-The callback function is declared as follows.
-
-	void callback(int num);
-
-
-Slot Detection
-==============
-
-This function returns the slot ID of the provided bridge.
-
-	int vme_slot_get(struct vme_dev *dev);

+ * This allocator is designed for use with zcache and zram. Thus, the
+ * allocator is supposed to work well under low memory conditions. In
+ * particular, it never attempts higher order page allocation which is
+ * very likely to fail under memory pressure. On the other hand, if we
+ * just use single (0-order) pages, it would suffer from very high
+ * fragmentation -- any object of size PAGE_SIZE/2 or larger would occupy
+ * an entire page. This was one of the major issues with its predecessor
+ * (xvmalloc).
+ *
+ * To overcome these issues, zsmalloc allocates a bunch of 0-order pages
+ * and links them together using various 'struct page' fields. These linked
+ * pages act as a single higher-order page i.e. an object can span 0-order
+ * page boundaries. The code refers to these linked pages as a single entity
+ * called zspage.
+ *
+ * Following is how we use various fields and flags of underlying
+ * struct page(s) to form a zspage.
+ *
+ * Usage of struct page fields:
+ *	page->first_page: points to the first component (0-order) page
+ *	page->index (union with page->freelist): offset of the first object
+ *		starting in this page. For the first page, this is
+ *		always 0, so we use this field (aka freelist) to point
+ *		to the first free object in zspage.
+ *	page->lru: links together all component pages (except the first page)
+ *		of a zspage
+ *
+ *	For _first_ page only:
+ *
+ *	page->private (union with page->first_page): refers to the
+ *		component page after the first page
+ *	page->freelist: points to the first free object in zspage.
+ *		Free objects are linked together using in-place
+ *		metadata.
+ *	page->objects: maximum number of objects we can store in this
+ *		zspage (class->zspage_order * PAGE_SIZE / class->size)
+ *	page->lru: links together first pages of various zspages.
+ *		Basically forming list of zspages in a fullness group.
+ *	page->mapping: class index and fullness group of the zspage
+ *
+ * Usage of struct page flags:
+ *	PG_private: identifies the first component page
+ *	PG_private2: identifies the last component page
