+ ********************************************************************/
+
+/*
+ * 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 transciever.
+ * 	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

 /*
- * History:
- * v0.01:  Initial version
- *	   only tested on Alpha Noname Board
- * v0.02:  changed IRQ handling for new interrupt scheme (dev_id)
- *	   tested on a ASUS SP3G
- * v0.10:  fixed an odd problem with the 79C974 in a Compaq Deskpro XL
- *	   looks like the 974 doesn't like stopping and restarting in a
- *	   short period of time; now we do a reinit of the lance; the
- *	   bug was triggered by doing ifconfig eth0 <ip> broadcast <addr>
- *	   and hangs the machine (thanks to Klaus Liedl for debugging)
- * v0.12:  by suggestion from Donald Becker: Renamed driver to pcnet32,
- *	   made it standalone (no need for lance.c)
- * v0.13:  added additional PCI detecting for special PCI devices (Compaq)
- * v0.14:  stripped down additional PCI probe (thanks to David C Niemi
- *	   and sveneric@xs4all.nl for testing this on their Compaq boxes)
- * v0.15:  added 79C965 (VLB) probe
- *	   added interrupt sharing for PCI chips
- * v0.16:  fixed set_multicast_list on Alpha machines
- * v0.17:  removed hack from dev.c; now pcnet32 uses ethif_probe in Space.c
- * v0.19:  changed setting of autoselect bit
- * v0.20:  removed additional Compaq PCI probe; there is now a working one
- *	   in arch/i386/bios32.c
- * v0.21:  added endian conversion for ppc, from work by cort@cs.nmt.edu
- * v0.22:  added printing of status to ring dump
- * v0.23:  changed enet_statistics to net_devive_stats
- * v0.90:  added multicast filter
- *	   added module support
- *	   changed irq probe to new style
- *	   added PCnetFast chip id
- *	   added fix for receive stalls with Intel saturn chipsets
- *	   added in-place rx skbs like in the tulip driver
- *	   minor cleanups
- * v0.91:  added PCnetFast+ chip id
- *	   back port to 2.0.x
- * v1.00:  added some stuff from Donald Becker's 2.0.34 version
- *	   added support for byte counters in net_dev_stats
- * v1.01:  do ring dumps, only when debugging the driver
- *	   increased the transmit timeout
- * v1.02:  fixed memory leak in pcnet32_init_ring()
- * v1.10:  workaround for stopped transmitter
- *	   added port selection for modules
- *	   detect special T1/E1 WAN card and setup port selection
- * v1.11:  fixed wrong checking of Tx errors
- * v1.20:  added check of return value kmalloc (cpeterso@cs.washington.edu)
- *	   added save original kmalloc addr for freeing (mcr@solidum.com)
- *	   added support for PCnetHome chip (joe@MIT.EDU)
- *	   rewritten PCI card detection
- *	   added dwio mode to get driver working on some PPC machines
- * v1.21:  added mii selection and mii ioctl
- * v1.22:  changed pci scanning code to make PPC people happy
- *	   fixed switching to 32bit mode in pcnet32_open() (thanks
- *	   to Michael Richard <mcr@solidum.com> for noticing this one)
- *	   added sub vendor/device id matching (thanks again to
- *	   Michael Richard <mcr@solidum.com>)
- *	   added chip id for 79c973/975 (thanks to Zach Brown <zab@zabbo.net>)
- * v1.23   fixed small bug, when manual selecting MII speed/duplex
- * v1.24   Applied Thomas' patch to use TxStartPoint and thus decrease TxFIFO
- *	   underflows.	Added tx_start_pt module parameter. Increased
- *	   TX_RING_SIZE from 16 to 32.	Added #ifdef'd code to use DXSUFLO
- *	   for FAST[+] chipsets. <kaf@fc.hp.com>
- * v1.24ac Added SMP spinlocking - Alan Cox <alan@redhat.com>
- * v1.25kf Added No Interrupt on successful Tx for some Tx's <kaf@fc.hp.com>
- * v1.26   Converted to pci_alloc_consistent, Jamey Hicks / George France
- *                                           <jamey@crl.dec.com>
- * -	   Fixed a few bugs, related to running the controller in 32bit mode.

- *	The following low power modes are available:
- *		
- *		- Coma Mode (Deep Sleep):
- *			Power consumption: ~15 - 30 mW
- *			The PHY cannot wake up on its own.
- *
- *		- IEEE 22.2.4.1.5 compatible power down mode
- *			Power consumption: ~240 mW
- *			The PHY cannot wake up on its own.
- *
- *		- energy detect mode
- *			Power consumption: ~160 mW
- *			The PHY can wake up on its own by detecting activity
- *			on the CAT 5 cable.
- *
- *		- energy detect plus mode
- *			Power consumption: ~150 mW
- *			The PHY can wake up on its own by detecting activity
- *			on the CAT 5 cable.
- *			Connected devices can be woken up by sending normal link
- *			pulses every one second.
