-/* The documentation for this chip is allegedly released */
-/* However I have not seen it, not have I managed to contact */
-/* anyone who has. HOWEVER the chip bears a striking resemblance */
-/* to the IrDA controller in the Toshiba RISC TMPR3922 chip */
-/* the documentation for this is freely available at */
-/* http://www.madingley.org/james/resources/toshoboe/TMPR3922.pdf */
-/* The mapping between the registers in that document and the */
-/* Registers in the 701 oboe chip are as follows */
-
-
-/* 3922 reg 701 regs, by bit numbers */
-/* 7- 0 15- 8 24-16 31-25 */
-/* $28 0x0 0x1 */

-/* documentation would suggest that a write of 0x1 to 0x8 */
-/* would be more appropriate. */
-/* */
-/* 3. This assignment is tenuous at best, register 0xe seems to */

-/* if either of the lower two bits are set the chip seems to */

-/* 6. The remaining registers: 0x6 and 0x3 appear to be */
-/* reserved parts of 16 or 32 bit registersthe remainder */
-/* 0xa 0xb 0x1e 0x1f could possibly be (by their behaviour) */
-/* the Unicast Filter register at $58. */

- *
- * As of kernel 2.5.20, this is the state of compliance and testing of
- * this driver (irda-usb) with regards to the USB low level drivers...
- *
- * This driver has been tested SUCCESSFULLY with the following drivers :
- * o usb-uhci-hcd (For Intel/Via USB controllers)
- * o uhci-hcd (Alternate/JE driver for Intel/Via USB controllers)
- * o ohci-hcd (For other USB controllers)
- *
- * This driver has NOT been tested with the following drivers :
- * o ehci-hcd (USB 2.0 controllers)
- *
- * Note that all HCD drivers do URB_ZERO_PACKET and timeout properly,
- * so we don't have to worry about that anymore.
- * One common problem is the failure to set the address on the dongle,
- * but this happens before the driver gets loaded...

-/*
- * This is my current (2007-04-25) understanding of how this dongle is supposed
- * to work. This is based on reverse-engineering and examination of the packet
- * data sent and received by the WinXP driver using USBSnoopy. Feel free to
- * update here as more of this dongle is known:
- *
- * General: Unlike the other USB IrDA dongles, this particular dongle exposes,
- * not two bulk (in and out) endpoints, but two *interrupt* ones. This dongle,
- * like the bulk based ones (stir4200.c and mcs7780.c), requires polling in
- * order to receive data.
- * Transmission: Just like stir4200, this dongle uses a raw stream of data,
- * which needs to be wrapped and escaped in a similar way as in stir4200.c.
- * Reception: Poll-based, as in stir4200. Each read returns the contents of a
- * 8-byte buffer, of which the first byte (LSB) indicates the number of bytes
- * (1-7) of valid data contained within the remaining 7 bytes. For example, if
- * the buffer had the following contents:
- * 06 ff ff ff c0 01 04 aa
- * This means that (06) there are 6 bytes of valid data. The byte 0xaa at the
- * end is garbage (left over from a previous reception) and is discarded.
- * If a read returns an "impossible" value as the length of valid data (such as
- * 0x36) in the first byte, then the buffer is uninitialized (as is the case of
- * first plug-in) and its contents should be discarded. There is currently no
- * evidence that the top 5 bits of the 1st byte of the buffer can have values
- * other than 0 once reception begins.
- * Once valid bytes are collected, the assembled stream is a sequence of
- * wrapped IrDA frames that is unwrapped and unescaped as in stir4200.c.
- * BIG FAT WARNING: the dongle does *not* reset the RX buffer in any way after
- * a successful read from the host, which means that in absence of further
- * reception, repeated reads from the dongle will return the exact same
- * contents repeatedly. Attempts to be smart and cache a previous read seem
- * to result in corrupted packets, so this driver depends on the unwrap logic
- * to sort out any repeated reads.
- * Speed change: no commands observed so far to change speed, assumed fixed
- * 9600bps (SIR).

- * Following is my most current (2007-07-17) understanding of how the Kingsun
- * KS-959 dongle is supposed to work. This information was deduced by
- * reverse-engineering and examining the USB traffic captured with USBSnoopy
- * from the WinXP driver. Feel free to update here as more of the dongle is
- * known.
- *
- * My most sincere thanks must go to Domen Puncer <domen@coderock.org> for
- * invaluable help in cracking the obfuscation and padding required for this
- * dongle.
- *
- * General: This dongle exposes one interface with one interrupt IN endpoint.
- * However, the interrupt endpoint is NOT used at all for this dongle. Instead,
- * this dongle uses control transfers for everything, including sending and
- * receiving the IrDA frame data. Apparently the interrupt endpoint is just a
- * dummy to ensure the dongle has a valid interface to present to the PC.And I
- * thought the DonShine dongle was weird... In addition, this dongle uses
- * obfuscation (?!?!), applied at the USB level, to hide the traffic, both sent
- * and received, from the dongle. I call it obfuscation because the XOR keying
- * and padding required to produce an USB traffic acceptable for the dongle can
- * not be explained by any other technical requirement.
- *
- * Transmission: To transmit an IrDA frame, the driver must prepare a control
- * URB with the following as a setup packet:
- * bRequestType USB_DIR_OUT | USB_TYPE_CLASS | USB_RECIP_INTERFACE
- * bRequest 0x09
- * wValue <length of valid data before padding, little endian>
- * wIndex 0x0000
- * wLength <length of padded data>
- * The payload packet must be manually wrapped and escaped (as in stir4200.c),
- * then padded and obfuscated before being sent. Both padding and obfuscation
- * are implemented in the procedure obfuscate_tx_buffer(). Suffice to say, the
- * designer/programmer of the dongle used his name as a source for the
- * obfuscation. WTF?!
- * Apparently the dongle cannot handle payloads larger than 256 bytes. The
- * driver has to perform fragmentation in order to send anything larger than
- * this limit.
- *
- * Reception: To receive data, the driver must poll the dongle regularly (like
- * kingsun-sir.c) with control URBs and the following as a setup packet:
- * bRequestType USB_DIR_IN | USB_TYPE_CLASS | USB_RECIP_INTERFACE
- * bRequest 0x01
- * wValue 0x0200
- * wIndex 0x0000
- * wLength 0x0800 (size of available buffer)
- * If there is data to be read, it will be returned as the response payload.
- * This data is (apparently) not padded, but it is obfuscated. To de-obfuscate
- * it, the driver must XOR every byte, in sequence, with a value that starts at
- * 1 and is incremented with each byte processed, and then with 0x55. The value
- * incremented with each byte processed overflows as an unsigned char. The
- * resulting bytes form a wrapped SIR frame that is unwrapped and unescaped
- * as in stir4200.c The incremented value is NOT reset with each frame, but is
- * kept across the entire session with the dongle. Also, the dongle inserts an
- * extra garbage byte with value 0x95 (after decoding) every 0xff bytes, which
- * must be skipped.
- *
- * Speed change: To change the speed of the dongle, the driver prepares a
- * control URB with the following as a setup packet:
- * bRequestType USB_DIR_OUT | USB_TYPE_CLASS | USB_RECIP_INTERFACE
- * bRequest 0x09
- * wValue 0x0200
- * wIndex 0x0001
- * wLength 0x0008 (length of the payload)
- * The payload is a 8-byte record, apparently identical to the one used in
- * drivers/usb/serial/cypress_m8.c to change speed:
- * __u32 baudSpeed;
- * unsigned int dataBits : 2; // 0 - 5 bits 3 - 8 bits
- * unsigned int : 1;
- * unsigned int stopBits : 1;
- * unsigned int parityEnable : 1;
- * unsigned int parityType : 1;
- * unsigned int : 1;
- * unsigned int reset : 1;
- * unsigned char reserved[3]; // set to 0
- *
- * For now only SIR speeds have been observed with this dongle. Therefore,
- * nothing is known on what changes (if any) must be done to frame wrapping /
- * unwrapping for higher than SIR speeds. This driver assumes no change is
- * necessary and announces support for all the way to 57600 bps. Although the
- * package announces support for up to 4MBps, tests with a Sony Ericcson K300
- * phone show corruption when receiving large frames at 115200 bps, the highest
- * speed announced by the phone. However, transmission at 115200 bps is OK. Go
- * figure. Since I don't know whether the phone or the dongle is at fault, max
- * announced speed is 57600 bps until someone produces a device that can run
- * at higher speeds with this dongle.

- * Following is my most current (2007-07-26) understanding of how the Kingsun
- * 07D0:4100 dongle (sometimes known as the MA-660) is supposed to work. This
- * information was deduced by examining the USB traffic captured with USBSnoopy
- * from the WinXP driver. Feel free to update here as more of the dongle is
- * known.
- *
- * General: This dongle exposes one interface with two interrupt endpoints, one
- * IN and one OUT. In this regard, it is similar to what the Kingsun/Donshine
- * dongle (07c0:4200) exposes. Traffic is raw and needs to be wrapped and
- * unwrapped manually as in stir4200, kingsun-sir, and ks959-sir.
- *
- * Transmission: To transmit an IrDA frame, it is necessary to wrap it, then
- * split it into multiple segments of up to 7 bytes each, and transmit each in
- * sequence. It seems that sending a single big block (like kingsun-sir does)
- * won't work with this dongle. Each segment needs to be prefixed with a value
- * equal to (unsigned char)0xF8 + <number of bytes in segment>, inside a payload
- * of exactly 8 bytes. For example, a segment of 1 byte gets prefixed by 0xF9,
- * and one of 7 bytes gets prefixed by 0xFF. The bytes at the end of the
- * payload, not considered by the prefix, are ignored (set to 0 by this
- * implementation).
- *
- * Reception: To receive data, the driver must poll the dongle regularly (like
- * kingsun-sir.c) with interrupt URBs. If data is available, it will be returned
- * in payloads from 0 to 8 bytes long. When concatenated, these payloads form
- * a raw IrDA stream that needs to be unwrapped as in stir4200 and kingsun-sir
- *
- * Speed change: To change the speed of the dongle, the driver prepares a
- * control URB with the following as a setup packet:
- * bRequestType USB_DIR_OUT | USB_TYPE_CLASS | USB_RECIP_INTERFACE
- * bRequest 0x09
- * wValue 0x0200
- * wIndex 0x0001
- * wLength 0x0008 (length of the payload)
- * The payload is a 8-byte record, apparently identical to the one used in
- * drivers/usb/serial/cypress_m8.c to change speed:
- * __u32 baudSpeed;
- * unsigned int dataBits : 2; // 0 - 5 bits 3 - 8 bits
- * unsigned int : 1;
- * unsigned int stopBits : 1;
- * unsigned int parityEnable : 1;
- * unsigned int parityType : 1;
- * unsigned int : 1;
- * unsigned int reset : 1;
- * unsigned char reserved[3]; // set to 0
- *
- * For now only SIR speeds have been observed with this dongle. Therefore,
- * nothing is known on what changes (if any) must be done to frame wrapping /
- * unwrapping for higher than SIR speeds. This driver assumes no change is
- * necessary and announces support for all the way to 115200 bps.

- * Belkin is selling a dongle called the SmartBeam.
- * In fact, there is two hardware version of this dongle, of course with
- * the same name and looking the exactly same (grrr...).
- * I guess that I've got the old one, because inside I don't have
- * a jumper for IrDA/ASK...
- *
- * As far as I can make it from info on their web site, the old dongle
- * support only 9600 b/s, which make our life much simpler as far as
- * the driver is concerned, but you might not like it very much ;-)
- * The new SmartBeam does 115 kb/s, and I've not tested it...
- *
- * Belkin claim that the correct driver for the old dongle (in Windows)
- * is the generic Parallax 9500a driver, but the Linux LiteLink driver
- * fails for me (probably because Linux-IrDA doesn't rate fallback),
- * so I created this really dumb driver...
- *
- * In fact, this driver doesn't do much. The only thing it does is to
- * prevent Linux-IrDA to use any other speed than 9600 b/s ;-) This
- * driver is called "old_belkin" so that when the new SmartBeam is supported
- * its driver can be called "belkin" instead of "new_belkin".
- *
- * Note : this driver was written without any info/help from Belkin,
- * so a lot of info here might be totally wrong. Blame me ;-)

- ********************************************************************/
-
-/*
- * This driver has currently only been tested on the IRWave IR320ST-2
- *
- * PROTOCOL:
- *
- * The protocol for talking to the TOIM3232 is quite easy, and is
- * designed to interface with RS232 with only level convertors. The
- * BR/~D line on the chip is brought high to signal 'command mode',
- * where a command byte is sent to select the baudrate of the RS232
- * interface and the pulse length of the IRDA output. When BR/~D
- * is brought low, the dongle then changes to the selected baudrate,
- * and the RS232 interface is used for data until BR/~D is brought
- * high again. The initial speed for the TOIMx323 after RESET is
- * 9600 baud. The baudrate for command-mode is the last selected
- * baud-rate, or 9600 after a RESET.
- *
- * The dongle I have (below) adds some extra hardware on the front end,
- * but this is mostly directed towards pariasitic power from the RS232
- * line rather than changing very much about how to communicate with
- * the TOIM3232.
- *
- * The protocol to talk to the TOIM4232 chipset seems to be almost
- * identical to the TOIM3232 (and the 4232 datasheet is more detailed)
- * so this code will probably work on that as well, although I haven't
- * tested it on that hardware.
- *
- * Target dongle variations that might be common:
- *
- * DTR and RTS function:
- * The data sheet for the 4232 has a sample implementation that hooks the
- * DTR and RTS lines to the RESET and BaudRate/~Data lines of the
- * chip (through line-converters). Given both DTR and RTS would have to
- * be held low in normal operation, and the TOIMx232 requires +5V to
- * signal ground, most dongle designers would almost certainly choose
- * an implementation that kept at least one of DTR or RTS high in
- * normal operation to provide power to the dongle, but will likely
- * vary between designs.
- *
- * User specified command bits:
- * There are two user-controllable output lines from the TOIMx232 that
- * can be set low or high by setting the appropriate bits in the
- * high-nibble of the command byte (when setting speed and pulse length).
- * These might be used to switch on and off added hardware or extra
- * dongle features.
- *
- *
- * Target hardware: IRWave IR320ST-2
- *
- * The IRWave IR320ST-2 is a simple dongle based on the Vishay/Temic
- * TOIM3232 SIR Endec and the Vishay/Temic TFDS4500 SIR IRDA transceiver.
- * It uses a hex inverter and some discrete components to buffer and
- * line convert the RS232 down to 5V.
- *
- * The dongle is powered through a voltage regulator, fed by a large
- * capacitor. To switch the dongle on, DTR is brought high to charge
- * the capacitor and drive the voltage regulator. DTR isn't associated
- * with any control lines on the TOIM3232. Parisitic power is also taken
- * from the RTS, TD and RD lines when brought high, but through resistors.
- * When DTR is low, the circuit might lose power even with RTS high.
- *
- * RTS is inverted and attached to the BR/~D input pin. When RTS
- * is high, BR/~D is low, and the TOIM3232 is in the normal 'data' mode.
- * RTS is brought low, BR/~D is high, and the TOIM3232 is in 'command
- * mode'.
- *
- * For some unknown reason, the RESET line isn't actually connected
- * to anything. This means to reset the dongle to get it to a known
- * state (9600 baud) you must drop DTR and RTS low, wait for the power
- * capacitor to discharge, and then bring DTR (and RTS for data mode)
- * high again, and wait for the capacitor to charge, the power supply
- * to stabilise, and the oscillator clock to stabilise.
- *
- * Fortunately, if the current baudrate is known, the chipset can
- * easily change speed by entering command mode without having to
- * reset the dongle first.
- *
- * Major Components:
- *
- * - Vishay/Temic TOIM3232 SIR Endec to change RS232 pulse timings
- * to IRDA pulse timings
- * - 3.6864MHz crystal to drive TOIM3232 clock oscillator
- * - DM74lS04M Inverting Hex line buffer for RS232 input buffering
- * and level conversion
- * - PJ2951AC 150mA voltage regulator
- * - Vishay/Temic TFDS4500 SIR IRDA front-end transceiver

- * This behaviour will probably work on dongles that have the RESET line connected,

-F01 Oct/02/02: Modify code for V0.11(move out back to back transfer)
-F02 Oct/28/02: Add SB device ID for 3147 and 3177.
- Comment :
- jul/09/2002 : only implement two kind of dongle currently.
- Oct/02/2002 : work on VT8231 and VT8233 .
- Aug/06/2003 : change driver format to pci driver .
-
-2004-02-16: <sda@bdit.de>
-- Removed unneeded 'legacy' pci stuff.
-- Make sure SIR mode is set (hw_init()) before calling mode-dependent stuff.
-- On speed change from core, don't send SIR frame with new speed.
- Use current speed and change speeds later.
-- Make module-param dongle_id actually work.
-- New dongle_id 17 (0x11): TDFS4500. Single-ended SIR only.
- Tested with home-grown PCB on EPIA boards.
-- Code cleanup.

- *
- * We select to operate using fixed MSTRPAGE=0, use ISA DMA
- * address restrictions to make the PCI BM api aware of this,
- * but ensure the hardware is dealing with real 32bit access.
- *
- * In detail:
- * The chip executes normal 32bit busmaster cycles, i.e.
- * drives all 32 address lines. These addresses however are
- * composed of [0:23] taken from various busaddr-pointers
- * and [24:31] taken from the MSTRPAGE register in the VLSI82C147
- * config space. Therefore _all_ busmastering must be
- * targeted to/from one single 16MB (busaddr-) superpage!
- * The point is to make sure all the allocations for memory
- * locations with busmaster access (ring descriptors, buffers)
- * are indeed bus-mappable to the same 16MB range (for x86 this
- * means they must reside in the same 16MB physical memory address
- * range). The only constraint we have which supports "several objects
- * mappable to common 16MB range" paradigma, is the old ISA DMA
- * restriction to the first 16MB of physical address range.
- * Hence the approach here is to enable PCI busmaster support using
- * the correct 32bit dma-mask used by the chip. Afterwards the device's
- * dma-mask gets restricted to 24bit, which must be honoured somehow by
- * all allocations for memory areas to be exposed to the chip ...
- *
- * Note:
- * Don't be surprised to get "Setting latency timer..." messages every
- * time when PCI busmastering is enabled for the chip.
- * The chip has its PCI latency timer RO fixed at 0 - which is not a
- * problem here, because it is never requesting _burst_ transactions.

- *
- * Notice that all functions that needs to access the chip in _any_
- * way, must save BSR register on entry, and restore it on exit.
- * It is _very_ important to follow this policy!
