- * Filename:      toim3232-sir.c
- * Version:       1.0
- * Description:   Implementation of dongles based on the Vishay/Temic
- * 		  TOIM3232 SIR Endec chipset. Currently only the
- * 		  IRWave IR320ST-2 is tested, although it should work
- * 		  with any TOIM3232 or TOIM4232 chipset based RS232
- * 		  dongle with minimal modification.
- * 		  Based heavily on the Tekram driver (tekram.c),
- * 		  with thanks to Dag Brattli and Martin Diehl.
- * Status:        Experimental.

-/*
- * 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 function resets the toim3232 dongle. Warning, this function

- * What we should do is:
- * 	0. Pull RESET high
- * 	1. Wait for at least 7us
- * 	2. Pull RESET low
- * 	3. Wait for at least 7us
- * 	4. Pull BR/~D high

- * 	6. Send control byte to set baud rate
- * 	7. Wait at least 1us after stop bit
- * 	8. Pull BR/~D low
- * 	9. Should then be in data mode
- *
- * Because the IR320ST-2 doesn't have the RESET line connected for some reason,
- * we'll have to do something else.
- *
- * The default speed after a RESET is 9600, so lets try just bringing it up in
- * data mode after switching it off, waiting for the supply capacitor to
- * discharge, and then switch it back on. This isn't actually pulling RESET
- * high, but it seems to have the same effect.
- *
- * This behaviour will probably work on dongles that have the RESET line connected,
- * but if not, add a flag for the IR320ST-2, and implment the above-listed proper

- * RTS is inverted and then fed to BR/~D, so to put it in programming mode, we
