staging: irda: remove the irda network stack and drivers

Browse Source 
No one has publicly stepped up to maintain this broken codebase for
devices that no one uses anymore, so let's just drop the whole thing.

If someone really wants/needs it, we can revert this and they can fix
the code up to work properly.

To use the IrDA protocols within Linux you will need to get a suitable copy
of the IrDA Utilities. More detailed information about these and associated
programs can be found on http://irda.sourceforge.net/
For more information about how to use the IrDA protocol stack, see the
Linux Infrared HOWTO by Werner Heuser <wehe@tuxmobil.org>:
<http://www.tuxmobil.org/Infrared-HOWTO/Infrared-HOWTO.html>
There is an active mailing list for discussing Linux-IrDA matters called
irda-users@lists.sourceforge.net

The irda code will be removed soon from the kernel tree as it is old and
obsolete and broken.
Don't worry about fixing up anything here, it's not needed.

comment "SIR device drivers"
config IRTTY_SIR
tristate "IrTTY (uses Linux serial driver)"
depends on IRDA && TTY
help
Say Y here if you want to build support for the IrTTY line
discipline. To compile it as a module, choose M here: the module
will be called irtty-sir. IrTTY makes it possible to use Linux's
own serial driver for all IrDA ports that are 16550 compatible.
Most IrDA chips are 16550 compatible so you should probably say Y
to this option. Using IrTTY will however limit the speed of the
connection to 115200 bps (IrDA SIR mode).
If unsure, say Y.
config BFIN_SIR

help
Say Y here if your want to enable SIR function on Blackfin UART
devices.
To activate this driver you can start irattach like:
"irattach irda0 -s"
Saying M, it will be built as a module named bfin_sir.
Note that you need to turn off one of the serial drivers for SIR
to use that UART.

Say Y here if you have an infrared device that connects to your
computer's serial port. These devices are called dongles. Then say Y
or M to the driver for your particular dongle below.
Note that the answer to this question won't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about serial dongles.

config USB_IRDA

Say Y here if you want to build support for the USB IrDA FIR Dongle
device driver. To compile it as a module, choose M here: the module
will be called irda-usb. IrDA-USB support the various IrDA USB
dongles available and most of their peculiarities. Those dongles
plug in the USB port of your computer, are plug and play, and
support SIR and FIR (4Mbps) speeds. On the other hand, those
dongles tend to be less efficient than a FIR chipset.
Please note that the driver is still experimental. And of course,
you will need both USB and IrDA support in your kernel...

Controller. The ALi M5123 FIR Controller is embedded in ALi M1543C,
M1535, M1535D, M1535+, M1535D South Bridge. This driver supports
SIR, MIR and FIR (4Mbps) speeds.

help
Say Y here if you want to build support for the VIA VT8231
and VIA VT1211 IrDA controllers, found on the motherboards using
those VIA chipsets. To use this controller, you will need
to plug a specific 5 pins FIR IrDA dongle in the specific
motherboard connector. The driver provides support for SIR, MIR

You will need to specify the 'dongle_id' module parameter to
indicate the FIR dongle attached to the controller.
To compile it as a module, choose M here: the module will be called
via-ircc.
config PXA_FICP
tristate "Intel PXA2xx Internal FICP"
depends on ARCH_PXA && IRDA
help
Say Y or M here if you want to build support for the PXA2xx
built-in IRDA interface which can support both SIR and FIR.
This driver relies on platform specific helper routines so
available capabilities may vary from one PXA2xx target to
another.
config MCS_FIR
tristate "MosChip MCS7780 IrDA-USB dongle"
depends on IRDA && USB
select CRC32
help
Say Y or M here if you want to build support for the MosChip
MCS7780 IrDA-USB bridge device driver.

/* 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 */
/* $2c SEE NOTE 1 */

/* */
/* 2. The M$ drivers do a write 0x1 to 0x9, however the 3922 */
/* 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 */
/* have bits arranged 0 0 0 R/W R/W R/W R/W R/W */
/* if either of the lower two bits are set the chip seems to */
/* switch off */
/* */
/* 4. Bits 7-4 seem to be different 4 seems just to be generic */
/* receiver busy flag */
/* */
/* 5. and 6. The IER and ISR have a different bit assignment */
/* The lower three bits of both read back as ones */
/* ISR is register 0xc, IER is register 0xd */
/* 7 6 5 4 3 2 1 0 */
/* 0xc: TxDone RxDone TxUndr RxOver SipRcv 1 1 1 */
/* 0xd: TxDone RxDone TxUndr RxOver SipRcv 1 1 1 */
/* TxDone xmitt done (generated only if generate interrupt bit */
/* is set in the ring) */
/* RxDone recv completed (or other recv condition if you set it */
/* up */
/* TxUnder underflow in Transmit FIFO */
/* RxOver overflow in Recv FIFO */
/* SipRcv received serial gap (or other condition you set) */
/* Interrupts are enabled by writing a one to the IER register */
/* Interrupts are cleared by writing a one to the ISR register */
/* */
/* 6. The remaining registers: 0x6 and 0x3 appear to be */

/* 0xa 0xb 0x1e 0x1f could possibly be (by their behaviour) */
/* the Unicast Filter register at $58. */

/* Maximum number of active URB on the Rx path
* This is the amount of buffers the we keep between the USB harware and the
* IrDA stack.
*
* Note : the network layer does also queue the packets between us and the
* IrDA stack, and is actually pretty fast and efficient in doing that.
* Therefore, we don't need to have a large number of URBs, and we can
* perfectly live happy with only one. We certainly don't need to keep the
* full IrTTP window around here...
* I repeat for those who have trouble to understand : 1 URB is plenty
* good enough to handle back-to-back (brickwalled) frames. I tried it,
* it works (it's the hardware that has trouble doing it).
*
* Having 2 URBs would allow the USB stack to process one URB while we take
* care of the other and then swap the URBs...
* On the other hand, increasing the number of URB will have penalities
* in term of latency and will interact with the link management in IrLAP...
