+			==========================
+
+Introduction
+------------
+
+  SPEAr (Structured Processor Enhanced Architecture).
+  weblink : http://www.st.com/spear
+
+  The ST Microelectronics SPEAr range of ARM9/CortexA9 System-on-Chip CPUs are
+  supported by the 'spear' platform of ARM Linux. Currently SPEAr300,
+  SPEAr310, SPEAr320 and SPEAr600 SOCs are supported. Support for the SPEAr13XX
+  series is in progress.
+
+  Hierarchy in SPEAr is as follows:
+
+  SPEAr (Platform)
+	- SPEAr3XX (3XX SOC series, based on ARM9)
+		- SPEAr300 (SOC)
+			- SPEAr300_EVB (Evaluation Board)
+		- SPEAr310 (SOC)
+			- SPEAr310_EVB (Evaluation Board)
+		- SPEAr320 (SOC)
+			- SPEAr320_EVB (Evaluation Board)
+	- SPEAr6XX (6XX SOC series, based on ARM9)
+		- SPEAr600 (SOC)
+			- SPEAr600_EVB (Evaluation Board)
+	- SPEAr13XX (13XX SOC series, based on ARM CORTEXA9)
+		- SPEAr1300 (SOC)
+
+  Configuration
+  -------------
+
+  A generic configuration is provided for each machine, and can be used as the
+  default by
+	make spear600_defconfig
+	make spear300_defconfig
+	make spear310_defconfig
+	make spear320_defconfig
+
+  Layout
+  ------
+
+  The common files for multiple machine families (SPEAr3XX, SPEAr6XX and
+  SPEAr13XX) are located in the platform code contained in arch/arm/plat-spear
+  with headers in plat/.
+
+  Each machine series have a directory with name arch/arm/mach-spear followed by
+  series name. Like mach-spear3xx, mach-spear6xx and mach-spear13xx.
+
+  Common file for machines of spear3xx family is mach-spear3xx/spear3xx.c and for
+  spear6xx is mach-spear6xx/spear6xx.c. mach-spear* also contain soc/machine
+  specific files, like spear300.c, spear310.c, spear320.c and spear600.c.
+  mach-spear* also contains board specific files for each machine type.

+The padata parallel execution mechanism
+Last updated for 2.6.34
+
+Padata is a mechanism by which the kernel can farm work out to be done in
+parallel on multiple CPUs while retaining the ordering of tasks.  It was
+developed for use with the IPsec code, which needs to be able to perform
+encryption and decryption on large numbers of packets without reordering
+those packets.  The crypto developers made a point of writing padata in a
+sufficiently general fashion that it could be put to other uses as well.
+
+The first step in using padata is to set up a padata_instance structure for
+overall control of how tasks are to be run:
+
+    #include <linux/padata.h>
+
+    struct padata_instance *padata_alloc(const struct cpumask *cpumask,
+				         struct workqueue_struct *wq);
+
+The cpumask describes which processors will be used to execute work
+submitted to this instance.  The workqueue wq is where the work will
+actually be done; it should be a multithreaded queue, naturally.
+
+There are functions for enabling and disabling the instance:
+
+    void padata_start(struct padata_instance *pinst);
+    void padata_stop(struct padata_instance *pinst);
+
+These functions literally do nothing beyond setting or clearing the
+"padata_start() was called" flag; if that flag is not set, other functions
+will refuse to work.
+
+The list of CPUs to be used can be adjusted with these functions:
+
+    int padata_set_cpumask(struct padata_instance *pinst,
+			   cpumask_var_t cpumask);
+    int padata_add_cpu(struct padata_instance *pinst, int cpu);
+    int padata_remove_cpu(struct padata_instance *pinst, int cpu);
+
+Changing the CPU mask has the look of an expensive operation, though, so it
+probably should not be done with great frequency.
+
+Actually submitting work to the padata instance requires the creation of a
+padata_priv structure:
+
+    struct padata_priv {
+        /* Other stuff here... */
+	void                    (*parallel)(struct padata_priv *padata);
+	void                    (*serial)(struct padata_priv *padata);
+    };
+
+This structure will almost certainly be embedded within some larger
+structure specific to the work to be done.  Most its fields are private to
+padata, but the structure should be zeroed at initialization time, and the
+parallel() and serial() functions should be provided.  Those functions will
+be called in the process of getting the work done as we will see
+momentarily.
+
+The submission of work is done with:
+
+    int padata_do_parallel(struct padata_instance *pinst,
+		           struct padata_priv *padata, int cb_cpu);
+
+The pinst and padata structures must be set up as described above; cb_cpu
+specifies which CPU will be used for the final callback when the work is
+done; it must be in the current instance's CPU mask.  The return value from
+padata_do_parallel() is a little strange; zero is an error return
+indicating that the caller forgot the padata_start() formalities.  -EBUSY
+means that somebody, somewhere else is messing with the instance's CPU
+mask, while -EINVAL is a complaint about cb_cpu not being in that CPU mask.
+If all goes well, this function will return -EINPROGRESS, indicating that
+the work is in progress.
+
+Each task submitted to padata_do_parallel() will, in turn, be passed to
+exactly one call to the above-mentioned parallel() function, on one CPU, so
+true parallelism is achieved by submitting multiple tasks.  Despite the
+fact that the workqueue is used to make these calls, parallel() is run with
+software interrupts disabled and thus cannot sleep.  The parallel()
+function gets the padata_priv structure pointer as its lone parameter;
+information about the actual work to be done is probably obtained by using
+container_of() to find the enclosing structure.
+
+Note that parallel() has no return value; the padata subsystem assumes that
+parallel() will take responsibility for the task from this point.  The work
+need not be completed during this call, but, if parallel() leaves work
+outstanding, it should be prepared to be called again with a new job before
+the previous one completes.  When a task does complete, parallel() (or
+whatever function actually finishes the job) should inform padata of the
+fact with a call to:
+
+    void padata_do_serial(struct padata_priv *padata);
+
+At some point in the future, padata_do_serial() will trigger a call to the
+serial() function in the padata_priv structure.  That call will happen on
+the CPU requested in the initial call to padata_do_parallel(); it, too, is
+done through the workqueue, but with local software interrupts disabled.
+Note that this call may be deferred for a while since the padata code takes
+pains to ensure that tasks are completed in the order in which they were
+submitted.
+
+The one remaining function in the padata API should be called to clean up
+when a padata instance is no longer needed:
+
+    void padata_free(struct padata_instance *pinst);
+
+This function will busy-wait while any remaining tasks are completed, so it
+might be best not to call it while there is work outstanding.  Shutting
+down the workqueue, if necessary, should be done separately.

 Interfaces for Entering System Sleep States
 ===========================================
-Most of the programming interfaces a device driver needs to know about
-relate to that first model:  entering a system-wide low power state,
-rather than just minimizing power consumption by one device.
-
-
-Bus Driver Methods
-------------------
-The core methods to suspend and resume devices reside in struct bus_type.
-These are mostly of interest to people writing infrastructure for busses
-like PCI or USB, or because they define the primitives that device drivers
-may need to apply in domain-specific ways to their devices:
-
-struct bus_type {
-	...
-	int  (*suspend)(struct device *dev, pm_message_t state);
-	int  (*resume)(struct device *dev);
+There are programming interfaces provided for subsystems (bus type, device type,
+device class) and device drivers to allow them to participate in the power
+management of devices they are concerned with.  These interfaces cover both
+system sleep and runtime power management.
+
+
+Device Power Management Operations
+----------------------------------
+Device power management operations, at the subsystem level as well as at the
+device driver level, are implemented by defining and populating objects of type
+struct dev_pm_ops:
+
+struct dev_pm_ops {
+	int (*prepare)(struct device *dev);
+	void (*complete)(struct device *dev);
+	int (*suspend)(struct device *dev);
+	int (*resume)(struct device *dev);

-Bus drivers implement those methods as appropriate for the hardware and
-the drivers using it; PCI works differently from USB, and so on.  Not many
-people write bus drivers; most driver code is a "device driver" that
-builds on top of bus-specific framework code.
+This structure is defined in include/linux/pm.h and the methods included in it
+are also described in that file.  Their roles will be explained in what follows.
+For now, it should be sufficient to remember that the last three methods are
+specific to runtime power management while the remaining ones are used during
+system-wide power transitions.
 
-For more information on these driver calls, see the description later;
-they are called in phases for every device, respecting the parent-child
-sequencing in the driver model tree.  Note that as this is being written,
-only the suspend() and resume() are widely available; not many bus drivers
-leverage all of those phases, or pass them down to lower driver levels.
+There also is a deprecated "old" or "legacy" interface for power management
+operations available at least for some subsystems.  This approach does not use
+struct dev_pm_ops objects and it is suitable only for implementing system sleep
+power management methods.  Therefore it is not described in this document, so
+please refer directly to the source code for more information about it.
 
 
-/sys/devices/.../power/wakeup files
------------------------------------
-All devices in the driver model have two flags to control handling of
-wakeup events, which are hardware signals that can force the device and/or
-system out of a low power state.  These are initialized by bus or device
-driver code using device_init_wakeup(dev,can_wakeup).
+Subsystem-Level Methods
+-----------------------
+The core methods to suspend and resume devices reside in struct dev_pm_ops
+pointed to by the pm member of struct bus_type, struct device_type and
+struct class.  They are mostly of interest to the people writing infrastructure
+for buses, like PCI or USB, or device type and device class drivers.
 
-The "can_wakeup" flag just records whether the device (and its driver) can
-physically support wakeup events.  When that flag is clear, the sysfs
-"wakeup" file is empty, and device_may_wakeup() returns false.
+Bus drivers implement these methods as appropriate for the hardware and the
+drivers using it; PCI works differently from USB, and so on.  Not many people
+write subsystem-level drivers; most driver code is a "device driver" that builds
+on top of bus-specific framework code.
 
-For devices that can issue wakeup events, a separate flag controls whether
-that device should try to use its wakeup mechanism.  The initial value of
-device_may_wakeup() will be true, so that the device's "wakeup" file holds
-the value "enabled".  Userspace can change that to "disabled" so that
-device_may_wakeup() returns false; or change it back to "enabled" (so that
-it returns true again).
+For more information on these driver calls, see the description later;
+they are called in phases for every device, respecting the parent-child
+sequencing in the driver model tree.
 
 
-EXAMPLE:  PCI Device Driver Methods
+/sys/devices/.../power/wakeup files
 -----------------------------------
-PCI framework software calls these methods when the PCI device driver bound
-to a device device has provided them:
-
-struct pci_driver {
-	...
-	int  (*suspend)(struct pci_device *pdev, pm_message_t state);
-	int  (*suspend_late)(struct pci_device *pdev, pm_message_t state);
+All devices in the driver model have two flags to control handling of wakeup
+events (hardware signals that can force the device and/or system out of a low
+power state).  These flags are initialized by bus or device driver code using
+device_set_wakeup_capable() and device_set_wakeup_enable(), defined in
+include/linux/pm_wakeup.h.
 
-	int  (*resume_early)(struct pci_device *pdev);
-	int  (*resume)(struct pci_device *pdev);
-};
-
-Drivers will implement those methods, and call PCI-specific procedures
-like pci_set_power_state(), pci_enable_wake(), pci_save_state(), and
-pci_restore_state() to manage PCI-specific mechanisms.  (PCI config space
-could be saved during driver probe, if it weren't for the fact that some
-systems rely on userspace tweaking using setpci.)  Devices are suspended
-before their bridges enter low power states, and likewise bridges resume
-before their devices.
-
-
-Upper Layers of Driver Stacks
------------------------------
-Device drivers generally have at least two interfaces, and the methods
-sketched above are the ones which apply to the lower level (nearer PCI, USB,
-or other bus hardware).  The network and block layers are examples of upper
-level interfaces, as is a character device talking to userspace.
-
-Power management requests normally need to flow through those upper levels,
-which often use domain-oriented requests like "blank that screen".  In
-some cases those upper levels will have power management intelligence that
-relates to end-user activity, or other devices that work in cooperation.
-
-When those interfaces are structured using class interfaces, there is a
-standard way to have the upper layer stop issuing requests to a given
-class device (and restart later):
-
-struct class {
-	...
-	int  (*suspend)(struct device *dev, pm_message_t state);
-	int  (*resume)(struct device *dev);
-};
-
-Those calls are issued in specific phases of the process by which the
-system enters a low power "suspend" state, or resumes from it.

-
-Calling Drivers to Enter System Sleep States
-============================================
-When the system enters a low power state, each device's driver is asked
-to suspend the device by putting it into state compatible with the target
+The "can_wakeup" flag just records whether the device (and its driver) can
+physically support wakeup events.  The device_set_wakeup_capable() routine
+affects this flag.  The "should_wakeup" flag controls whether the device should
+try to use its wakeup mechanism.  device_set_wakeup_enable() affects this flag;
+for the most part drivers should not change its value.  The initial value of
+should_wakeup is supposed to be false for the majority of devices; the major
+exceptions are power buttons, keyboards, and Ethernet adapters whose WoL
+(wake-on-LAN) feature has been set up with ethtool.
+
+Whether or not a device is capable of issuing wakeup events is a hardware
+matter, and the kernel is responsible for keeping track of it.  By contrast,
+whether or not a wakeup-capable device should issue wakeup events is a policy
+decision, and it is managed by user space through a sysfs attribute: the
+power/wakeup file.  User space can write the strings "enabled" or "disabled" to
+set or clear the should_wakeup flag, respectively.  Reads from the file will
+return the corresponding string if can_wakeup is true, but if can_wakeup is
+false then reads will return an empty string, to indicate that the device
+doesn't support wakeup events.  (But even though the file appears empty, writes
+will still affect the should_wakeup flag.)
+
+The device_may_wakeup() routine returns true only if both flags are set.
+Drivers should check this routine when putting devices in a low-power state
+during a system sleep transition, to see whether or not to enable the devices'
+wakeup mechanisms.  However for runtime power management, wakeup events should
+be enabled whenever the device and driver both support them, regardless of the
+should_wakeup flag.
+
+
+/sys/devices/.../power/control files
+------------------------------------
+Each device in the driver model has a flag to control whether it is subject to
+runtime power management.  This flag, called runtime_auto, is initialized by the
+bus type (or generally subsystem) code using pm_runtime_allow() or
+pm_runtime_forbid(); the default is to allow runtime power management.
+
+The setting can be adjusted by user space by writing either "on" or "auto" to
+the device's power/control sysfs file.  Writing "auto" calls pm_runtime_allow(),
+setting the flag and allowing the device to be runtime power-managed by its
+driver.  Writing "on" calls pm_runtime_forbid(), clearing the flag, returning
+the device to full power if it was in a low-power state, and preventing the
+device from being runtime power-managed.  User space can check the current value
+of the runtime_auto flag by reading the file.
+
+The device's runtime_auto flag has no effect on the handling of system-wide
+power transitions.  In particular, the device can (and in the majority of cases

+System Power Management Phases
+------------------------------
+Suspending or resuming the system is done in several phases.  Different phases

+hibernation state ("suspend-to-disk").  Each phase involves executing callbacks
+for every device before the next phase begins.  Not all busses or classes
+support all these callbacks and not all drivers use all the callbacks.  The
+various phases always run after tasks have been frozen and before they are
+unfrozen.  Furthermore, the *_noirq phases run at a time when IRQ handlers have
+been disabled (except for those marked with the IRQ_WAKEUP flag).
 
-The phases are seen by driver notifications issued in this order:
+Most phases use bus, type, and class callbacks (that is, methods defined in
+dev->bus->pm, dev->type->pm, and dev->class->pm).  The prepare and complete
+phases are exceptions; they use only bus callbacks.  When multiple callbacks
+are used in a phase, they are invoked in the order: <class, type, bus> during
+power-down transitions and in the opposite order during power-up transitions.
+For example, during the suspend phase the PM core invokes

+Entering System Suspend
+-----------------------
+When the system goes into the standby or memory sleep state, the phases are:
+
+		prepare, suspend, suspend_noirq.
+
+    1.	The prepare phase is meant to prevent races by preventing new devices
+	from being registered; the PM core would never know that all the
+	children of a device had been suspended if new children could be
+	registered at will.  (By contrast, devices may be unregistered at any
+	time.)  Unlike the other suspend-related phases, during the prepare
+	phase the device tree is traversed top-down.
+
+	The prepare phase uses only a bus callback.  After the callback method
+	returns, no new children may be registered below the device.  The method
+	may also prepare the device or driver in some way for the upcoming
+	system power transition, but it should not put the device into a
+	low-power state.
+
+    2.	The suspend methods should quiesce the device to stop it from performing
+	I/O.  They also may save the device registers and put it into the
+	appropriate low-power state, depending on the bus type the device is on,
+	and they may enable wakeup events.
+
+    3.	The suspend_noirq phase occurs after IRQ handlers have been disabled,
+	which means that the driver's interrupt handler will not be called while
+	the callback method is running.  The methods should save the values of
+	the device's registers that weren't saved previously and finally put the
+	device into the appropriate low-power state.
+
+	The majority of subsystems and device drivers need not implement this
+	callback.  However, bus types allowing devices to share interrupt
+	vectors, like PCI, generally need it; otherwise a driver might encounter
+	an error during the suspend phase by fielding a shared interrupt
+	generated by some other device after its own device had been set to low
+	power.
+
+At the end of these phases, drivers should have stopped all I/O transactions
+(DMA, IRQs), saved enough state that they can re-initialize or restore previous
+state (as needed by the hardware), and placed the device into a low-power state.
+On many platforms they will gate off one or more clock sources; sometimes they
+will also switch off power supplies or reduce voltages.  (Drivers supporting
+runtime PM may already have performed some or all of these steps.)
+
+If device_may_wakeup(dev) returns true, the device should be prepared for
+generating hardware wakeup signals to trigger a system wakeup event when the
+system is in the sleep state.  For example, enable_irq_wake() might identify
+GPIO signals hooked up to a switch or other external hardware, and
+pci_enable_wake() does something similar for the PCI PME signal.
+
+If any of these callbacks returns an error, the system won't enter the desired
+low-power state.  Instead the PM core will unwind its actions by resuming all
+the devices that were suspended.
+
+
+Leaving System Suspend
+----------------------
+When resuming from standby or memory sleep, the phases are:
+
+		resume_noirq, resume, complete.
+
+    1.	The resume_noirq callback methods should perform any actions needed
+	before the driver's interrupt handlers are invoked.  This generally
+	means undoing the actions of the suspend_noirq phase.  If the bus type
+	permits devices to share interrupt vectors, like PCI, the method should
+	bring the device and its driver into a state in which the driver can
+	recognize if the device is the source of incoming interrupts, if any,
+	and handle them correctly.
+
+	For example, the PCI bus type's ->pm.resume_noirq() puts the device into
+	the full-power state (D0 in the PCI terminology) and restores the
+	standard configuration registers of the device.  Then it calls the
+	device driver's ->pm.resume_noirq() method to perform device-specific
+	actions.
+
+    2.	The resume methods should bring the the device back to its operating
+	state, so that it can perform normal I/O.  This generally involves
+	undoing the actions of the suspend phase.
+
+    3.	The complete phase uses only a bus callback.  The method should undo the
+	actions of the prepare phase.  Note, however, that new children may be
+	registered below the device as soon as the resume callbacks occur; it's
+	not necessary to wait until the complete phase.
+
+At the end of these phases, drivers should be as functional as they were before
+suspending: I/O can be performed using DMA and IRQs, and the relevant clocks are
+gated on.  Even if the device was in a low-power state before the system sleep
+because of runtime power management, afterwards it should be back in its
+full-power state.  There are multiple reasons why it's best to do this; they are
+discussed in more detail in Documentation/power/runtime_pm.txt.
 
-When any driver sees that its device_can_wakeup(dev), it should make sure
-to use the relevant hardware signals to trigger a system wakeup event.
-For example, enable_irq_wake() might identify GPIO signals hooked up to
-a switch or other external hardware, and pci_enable_wake() does something
-similar for PCI's PME# signal.
+However, the details here may again be platform-specific.  For example,
+some systems support multiple "run" states, and the mode in effect at
+the end of resume might not be the one which preceded suspension.
+That means availability of certain clocks or power supplies changed,
+which could easily affect how a driver works.
+
+Drivers need to be able to handle hardware which has been reset since the
+suspend methods were called, for example by complete reinitialization.
+This may be the hardest part, and the one most protected by NDA'd documents
+and chip errata.  It's simplest if the hardware state hasn't changed since
+the suspend was carried out, but that can't be guaranteed (in fact, it ususally
+is not the case).
+
+Drivers must also be prepared to notice that the device has been removed
+while the system was powered down, whenever that's physically possible.
+PCMCIA, MMC, USB, Firewire, SCSI, and even IDE are common examples of busses
+where common Linux platforms will see such removal.  Details of how drivers
+will notice and handle such removals are currently bus-specific, and often
+involve a separate thread.
+
+These callbacks may return an error value, but the PM core will ignore such
+errors since there's nothing it can do about them other than printing them in
+the system log.
+
+
+Entering Hibernation
+--------------------
+Hibernating the system is more complicated than putting it into the standby or
+memory sleep state, because it involves creating and saving a system image.
+Therefore there are more phases for hibernation, with a different set of
+callbacks.  These phases always run after tasks have been frozen and memory has
+been freed.
+
+The general procedure for hibernation is to quiesce all devices (freeze), create
+an image of the system memory while everything is stable, reactivate all
+devices (thaw), write the image to permanent storage, and finally shut down the
+system (poweroff).  The phases used to accomplish this are:
+
+	prepare, freeze, freeze_noirq, thaw_noirq, thaw, complete,
+	prepare, poweroff, poweroff_noirq
+
+    1.	The prepare phase is discussed in the "Entering System Suspend" section
+	above.
+
+    2.	The freeze methods should quiesce the device so that it doesn't generate
+	IRQs or DMA, and they may need to save the values of device registers.
+	However the device does not have to be put in a low-power state, and to
+	save time it's best not to do so.  Also, the device should not be
+	prepared to generate wakeup events.
+
+    3.	The freeze_noirq phase is analogous to the suspend_noirq phase discussed
+	above, except again that the device should not be put in a low-power
+	state and should not be allowed to generate wakeup events.
+
+At this point the system image is created.  All devices should be inactive and
+the contents of memory should remain undisturbed while this happens, so that the
+image forms an atomic snapshot of the system state.
+
+    4.	The thaw_noirq phase is analogous to the resume_noirq phase discussed
+	above.  The main difference is that its methods can assume the device is
+	in the same state as at the end of the freeze_noirq phase.
+
+    5.	The thaw phase is analogous to the resume phase discussed above.  Its
+	methods should bring the device back to an operating state, so that it
+	can be used for saving the image if necessary.
+
+    6.	The complete phase is discussed in the "Leaving System Suspend" section
+	above.
+
+At this point the system image is saved, and the devices then need to be
+prepared for the upcoming system shutdown.  This is much like suspending them
+before putting the system into the standby or memory sleep state, and the phases
+are similar.
+
+    7.	The prepare phase is discussed above.
+
+    8.	The poweroff phase is analogous to the suspend phase.
+
+    9.	The poweroff_noirq phase is analogous to the suspend_noirq phase.
+
+The poweroff and poweroff_noirq callbacks should do essentially the same things
+as the suspend and suspend_noirq callbacks.  The only notable difference is that
+they need not store the device register values, because the registers should
+already have been stored during the freeze or freeze_noirq phases.
+
+
+Leaving Hibernation
+-------------------
+Resuming from hibernation is, again, more complicated than resuming from a sleep
+state in which the contents of main memory are preserved, because it requires
+a system image to be loaded into memory and the pre-hibernation memory contents
+to be restored before control can be passed back to the image kernel.
+
+Although in principle, the image might be loaded into memory and the
+pre-hibernation memory contents restored by the boot loader, in practice this
+can't be done because boot loaders aren't smart enough and there is no
+established protocol for passing the necessary information.  So instead, the
+boot loader loads a fresh instance of the kernel, called the boot kernel, into
+memory and passes control to it in the usual way.  Then the boot kernel reads
+the system image, restores the pre-hibernation memory contents, and passes
+control to the image kernel.  Thus two different kernels are involved in
+resuming from hibernation.  In fact, the boot kernel may be completely different
+from the image kernel: a different configuration and even a different version.
+This has important consequences for device drivers and their subsystems.
+
+To be able to load the system image into memory, the boot kernel needs to
+include at least a subset of device drivers allowing it to access the storage
+medium containing the image, although it doesn't need to include all of the
+drivers present in the image kernel.  After the image has been loaded, the
+devices managed by the boot kernel need to be prepared for passing control back
+to the image kernel.  This is very similar to the initial steps involved in
+creating a system image, and it is accomplished in the same way, using prepare,
+freeze, and freeze_noirq phases.  However the devices affected by these phases
+are only those having drivers in the boot kernel; other devices will still be in
+whatever state the boot loader left them.
+
+Should the restoration of the pre-hibernation memory contents fail, the boot
+kernel would go through the "thawing" procedure described above, using the
+thaw_noirq, thaw, and complete phases, and then continue running normally.  This
+happens only rarely.  Most often the pre-hibernation memory contents are
+restored successfully and control is passed to the image kernel, which then
+becomes responsible for bringing the system back to the working state.
+
+To achieve this, the image kernel must restore the devices' pre-hibernation
+functionality.  The operation is much like waking up from the memory sleep
+state, although it involves different phases:
+
+	restore_noirq, restore, complete
+
+    1.	The restore_noirq phase is analogous to the resume_noirq phase.
+
+    2.	The restore phase is analogous to the resume phase.
+
+    3.	The complete phase is discussed above.
+
+The main difference from resume[_noirq] is that restore[_noirq] must assume the
+device has been accessed and reconfigured by the boot loader or the boot kernel.
+Consequently the state of the device may be different from the state remembered
+from the freeze and freeze_noirq phases.  The device may even need to be reset
+and completely re-initialized.  In many cases this difference doesn't matter, so
+the resume[_noirq] and restore[_norq] method pointers can be set to the same
+routines.  Nevertheless, different callback pointers are used in case there is a
+situation where it actually matters.
 
-If a driver (or bus, or class) fails it suspend method, the system won't
-enter the desired low power state; it will resume all the devices it's
-suspended so far.
 
-Note that drivers may need to perform different actions based on the target
-system lowpower/sleep state.  At this writing, there are only platform
-specific APIs through which drivers could determine those target states.
+System Devices
+--------------
+System devices (sysdevs) follow a slightly different API, which can be found in
+
+	include/linux/sysdev.h
+	drivers/base/sys.c
+
+System devices will be suspended with interrupts disabled, and after all other
+devices have been suspended.  On resume, they will be resumed before any other
+devices, and also with interrupts disabled.  These things occur in special
+"sysdev_driver" phases, which affect only system devices.
+
+Thus, after the suspend_noirq (or freeze_noirq or poweroff_noirq) phase, when
+the non-boot CPUs are all offline and IRQs are disabled on the remaining online
+CPU, then a sysdev_driver.suspend phase is carried out, and the system enters a
+sleep state (or a system image is created).  During resume (or after the image
+has been created or loaded) a sysdev_driver.resume phase is carried out, IRQs
+are enabled on the only online CPU, the non-boot CPUs are enabled, and the
+resume_noirq (or thaw_noirq or restore_noirq) phase begins.
+
+Code to actually enter and exit the system-wide low power state sometimes
+involves hardware details that are only known to the boot firmware, and
+may leave a CPU running software (from SRAM or flash memory) that monitors
+the system and manages its wakeup sequence.

+Power Management Notifiers
+--------------------------
+There are some operations that cannot be carried out by the power management
+callbacks discussed above, because the callbacks occur too late or too early.
+To handle these cases, subsystems and device drivers may register power

-Resuming Devices

-The phases are seen by driver notifications issued in this order:

-   1	bus.resume(dev) reverses the effects of bus.suspend().  This may

-	that has such a method.  Implementations may sleep.

-	This reverses the effects of class.suspend(), and would usually

-Examples:  USB hosts, system timer, system CPU
-----------------------------------------------
-USB host controllers make interesting, if complex, examples.  In many cases
-these have no work to do:  no USB devices are connected, or all of them are
-in the USB "suspend" state.  Linux host controller drivers can then disable
-periodic DMA transfers that would otherwise be a constant power drain on the
-memory subsystem, and enter a suspend state.  In power-aware controllers,
-entering that suspend state may disable the clock used with USB signaling,
-saving a certain amount of power.
-
-The controller will be woken from that state (with an IRQ) by changes to the
-signal state on the data lines of a given port, for example by an existing
-peripheral requesting "remote wakeup" or by plugging a new peripheral.  The
-same wakeup mechanism usually works from "standby" sleep states, and on some
-systems also from "suspend to RAM" (or even "suspend to disk") states.
-(Except that ACPI may be involved instead of normal IRQs, on some hardware.)
-
-System devices like timers and CPUs may have special roles in the platform
-power management scheme.  For example, system timers using a "dynamic tick"
-approach don't just save CPU cycles (by eliminating needless timer IRQs),
-but they may also open the door to using lower power CPU "idle" states that
-cost more than a jiffie to enter and exit.  On x86 systems these are states
-like "C3"; note that periodic DMA transfers from a USB host controller will
-also prevent entry to a C3 state, much like a periodic timer IRQ.
-
-That kind of runtime mechanism interaction is common.  "System On Chip" (SOC)
-processors often have low power idle modes that can't be entered unless
-certain medium-speed clocks (often 12 or 48 MHz) are gated off.  When the
-drivers gate those clocks effectively, then the system idle task may be able
-to use the lower power idle modes and thereby increase battery life.
-
-If the CPU can have a "cpufreq" driver, there also may be opportunities
-to shift to lower voltage settings and reduce the power cost of executing
-a given number of instructions.  (Without voltage adjustment, it's rare
-for cpufreq to save much power; the cost-per-instruction must go down.)
+A system-wide power transition can be started while some devices are in low
+power states due to runtime power management.  The system sleep PM callbacks
+should recognize such situations and react to them appropriately, but the
+necessary actions are subsystem-specific.
+
+In some cases the decision may be made at the subsystem level while in other
+cases the device driver may be left to decide.  In some cases it may be
+desirable to leave a suspended device in that state during a system-wide power
+transition, but in other cases the device must be put back into the full-power
+state temporarily, for example so that its system wakeup capability can be
+disabled.  This all depends on the hardware and the design of the subsystem and
+device driver in question.
+
+During system-wide resume from a sleep state it's best to put devices into the
+full-power state, as explained in Documentation/power/runtime_pm.txt.  Refer to
+that document for more information regarding this particular issue as well as
+for information on the device runtime power management framework in general.

+struct v4l2_fh
+--------------
+
+struct v4l2_fh provides a way to easily keep file handle specific data
+that is used by the V4L2 framework. Using v4l2_fh is optional for
+drivers.
+
+The users of v4l2_fh (in the V4L2 framework, not the driver) know
+whether a driver uses v4l2_fh as its file->private_data pointer by
+testing the V4L2_FL_USES_V4L2_FH bit in video_device->flags.
+
+Useful functions:
+
+- v4l2_fh_init()
+
+  Initialise the file handle. This *MUST* be performed in the driver's
+  v4l2_file_operations->open() handler.
+
+- v4l2_fh_add()
+
+  Add a v4l2_fh to video_device file handle list. May be called after
+  initialising the file handle.
+
+- v4l2_fh_del()
+
+  Unassociate the file handle from video_device(). The file handle
+  exit function may now be called.
+
+- v4l2_fh_exit()
+
+  Uninitialise the file handle. After uninitialisation the v4l2_fh
+  memory can be freed.
+
+struct v4l2_fh is allocated as a part of the driver's own file handle
+structure and is set to file->private_data in the driver's open
+function by the driver. Drivers can extract their own file handle
+structure by using the container_of macro. Example:
+
+struct my_fh {
+	int blah;
+	struct v4l2_fh fh;
+};
+
+...
+
+int my_open(struct file *file)
+{
+	struct my_fh *my_fh;
+	struct video_device *vfd;
+	int ret;
+
+	...
+
+	ret = v4l2_fh_init(&my_fh->fh, vfd);
+	if (ret)
+		return ret;
+
+	v4l2_fh_add(&my_fh->fh);
+
+	file->private_data = &my_fh->fh;
+
+	...
+}
+
+int my_release(struct file *file)
+{
+	struct v4l2_fh *fh = file->private_data;
+	struct my_fh *my_fh = container_of(fh, struct my_fh, fh);
+
+	...
+}
+
+V4L2 events
+-----------
+
+The V4L2 events provide a generic way to pass events to user space.
+The driver must use v4l2_fh to be able to support V4L2 events.
+
+Useful functions:
+
+- v4l2_event_alloc()
+
+  To use events, the driver must allocate events for the file handle. By
+  calling the function more than once, the driver may assure that at least n
+  events in total have been allocated. The function may not be called in
+  atomic context.
+
+- v4l2_event_queue()
+
+  Queue events to video device. The driver's only responsibility is to fill
+  in the type and the data fields. The other fields will be filled in by
+  V4L2.
+
+- v4l2_event_subscribe()
+
+  The video_device->ioctl_ops->vidioc_subscribe_event must check the driver
+  is able to produce events with specified event id. Then it calls
+  v4l2_event_subscribe() to subscribe the event.
+
+- v4l2_event_unsubscribe()
+
+  vidioc_unsubscribe_event in struct v4l2_ioctl_ops. A driver may use
+  v4l2_event_unsubscribe() directly unless it wants to be involved in
+  unsubscription process.
+
+  The special type V4L2_EVENT_ALL may be used to unsubscribe all events. The
+  drivers may want to handle this in a special way.
+
+- v4l2_event_pending()
+
+  Returns the number of pending events. Useful when implementing poll.
+
+Drivers do not initialise events directly. The events are initialised
+through v4l2_fh_init() if video_device->ioctl_ops->vidioc_subscribe_event is
+non-NULL. This *MUST* be performed in the driver's
+v4l2_file_operations->open() handler.
+
+Events are delivered to user space through the poll system call. The driver
+can use v4l2_fh->events->wait wait_queue_head_t as the argument for
+poll_wait().
+
+There are standard and private events. New standard events must use the
+smallest available event type. The drivers must allocate their events from
+their own class starting from class base. Class base is
+V4L2_EVENT_PRIVATE_START + n * 1000 where n is the lowest available number.
+The first event type in the class is reserved for future use, so the first
+available event type is 'class base + 1'.
+
+An example on how the V4L2 events may be used can be found in the OMAP
+3 ISP driver available at <URL:http://gitorious.org/omap3camera> as of
+writing this.

+ * @enabled:		refcount. positive if enabled, zero if disabled
+ * @rate:		fixed rate for clocks which don't implement
+ * 			ops->getrate
+ * @prcmu_cg_off:	address offset of the combined enable/disable register
+ * 			(used on u8500v1)
+ * @prcmu_cg_bit:	bit in the combined enable/disable register (used on
+ * 			u8500v1)
+ * @prcmu_cg_mgt:	address of the enable/disable register (used on
+ * 			u8500ed)
+ * @cluster:		peripheral cluster number
+ * @prcc_bus:		bit for the bus clock in the peripheral's CLKRST
+ * @prcc_kernel:	bit for the kernel clock in the peripheral's CLKRST.
+ * 			-1 if no kernel clock exists.
+ * @parent_cluster:	pointer to parent's cluster clk struct
+ * @parent_periph:	pointer to parent's peripheral clk struct
+ *
+ * Peripherals are organised into clusters, and each cluster has an associated
+ * bus clock.  Some peripherals also have a parent peripheral clock.
+ *
+ * In order to enable a clock for a peripheral, we need to enable:
+ * 	(1) the parent cluster (bus) clock at the PRCMU level
+ * 	(2) the parent peripheral clock (if any) at the PRCMU level
+ * 	(3) the peripheral's bus & kernel clock at the PRCC level
+ *
+ * (1) and (2) are handled by defining clk structs (DEFINE_PRCMU_CLK) for each
+ * of the cluster and peripheral clocks, and hooking these as the parents of
+ * the individual peripheral clocks.
+ *
+ * (3) is handled by specifying the bits in the PRCC control registers required
+ * to enable these clocks and modifying them in the ->enable and
+ * ->disable callbacks of the peripheral clocks (DEFINE_PRCC_CLK).
+ *
+ * This structure describes both the PRCMU-level clocks and PRCC-level clocks.
+ * The prcmu_* fields are only used for the PRCMU clocks, and the cluster,
+ * prcc, and parent pointers are only used for the PRCC-level clocks.

+	  Historically, the kernel has used strongly ordered mappings to

+	  so on these CPUs, this option is forced on.
+
+	  Multiple mappings with differing attributes is also unpredictable
+	  on ARMv6 CPUs, but since they do not have aggressive speculative
+	  prefetch, no harm appears to occur.
+
+	  However, drivers may be missing the necessary barriers for ARMv6,
+	  and therefore turning this on may result in unpredictable driver
+	  behaviour.  Therefore, we offer this as an option.
+

+ * This function is only enabled if acpi_gbl_enable_aml_debug_object is set, or
+ * if ACPI_LV_DEBUG_OBJECT is set in the acpi_dbg_level. Thus, in the normal
+ * operational case, stores to the debug object are ignored but can be easily

-
-    Copyright (C) 2005 Ben Gardner <bgardner@wabtec.com>
-
-    Based on eeprom.c
-
-    The MAX6875 has a bank of registers and two banks of EEPROM.
-    Address ranges are defined as follows:
-     * 0x0000 - 0x0046 = configuration registers
-     * 0x8000 - 0x8046 = configuration EEPROM
-     * 0x8100 - 0x82FF = user EEPROM
-
-    This driver makes the user EEPROM available for read.
-
-    The registers & config EEPROM should be accessed via i2c-dev.
-
-    The MAX6875 ignores the lowest address bit, so each chip responds to
-    two addresses - 0x50/0x51 and 0x52/0x53.
-
-    Note that the MAX6875 uses i2c_smbus_write_byte_data() to set the read
-    address, so this driver is destructive if loaded for the wrong EEPROM chip.
-

+Todo:
+	- Fix the loss of some blocks when receiving the video URB's
+	- Add a lock at tm6000_read_write_usb() to prevent two simultaneous access to the
+	  URB control transfers
+	- Properly add the locks at tm6000-video
+	- Add audio support
+	- Add vbi support
+	- Add IR support
+	- Do several cleanups
+	- I think that frame1/frame0 are inverted. This causes a funny effect at the image.
+	  the fix is trivial, but require some tests
+	- My tm6010 devices sometimes insist on stop working. I need to turn them off, removing
+	  from my machine and wait for a while for it to work again. I'm starting to think that
+	  it is an overheat issue - is there a workaround that we could do?
+	- Sometimes, tm6010 doesn't read eeprom at the proper time (hardware bug). So, the device
+	  got miss-detected as a "generic" tm6000. This can be really bad if the tuner is the
+	  Low Power one, as it may result on loading the high power firmware, that could damage
+	  the device. Maybe we may read eeprom to double check, when the device is marked as "generic"
+	- Coding Style fixes
+	- sparse cleanups

+ *     2.4.22 usb-uhci seems buggy for async unlinking and results in
+ *     oops.  in such a cse, pass async_unlink=0 option.
+ *   - the linked URBs would be preferred but not used so far because of
+ *     the instability of unlinking.
+ *   - type II is not supported properly.  there is no device which supports
+ *     this type *correctly*.  SB extigy looks as if it supports, but it's
+ *     indeed an AC3 stream packed in SPDIF frames (i.e. no real AC3 stream).

- *     2.4.22 usb-uhci seems buggy for async unlinking and results in
- *     oops.  in such a cse, pass async_unlink=0 option.
- *   - the linked URBs would be preferred but not used so far because of

- *   - type II is not supported properly.  there is no device which supports
- *     this type *correctly*.  SB extigy looks as if it supports, but it's
- *     indeed an AC3 stream packed in SPDIF frames (i.e. no real AC3 stream).
