* cs4232.c
|
|
||||||
*
|
|
||||||
* The low level driver for Crystal CS4232 based cards. The CS4232 is
|
|
||||||
* a PnP compatible chip which contains a CS4231A codec, SB emulation,
|
|
||||||
* a MPU401 compatible MIDI port, joystick and synthesizer and IDE CD-ROM
|
|
||||||
* interfaces. This is just a temporary driver until full PnP support
|
|
||||||
* gets implemented. Just the WSS codec, FM synth and the MIDI ports are
|
|
||||||
* supported. Other interfaces are left uninitialized.
|
|
||||||
*
|
|
||||||
* ifdef ...WAVEFRONT...
|
|
||||||
*
|
|
||||||
* Support is provided for initializing the WaveFront synth
|
|
||||||
* interface as well, which is logical device #4. Note that if
|
|
||||||
* you have a Tropez+ card, you probably don't need to setup
|
|
||||||
* the CS4232-supported MIDI interface, since it corresponds to
|
|
||||||
* the internal 26-pin header that's hard to access. Using this
|
|
||||||
* requires an additional IRQ, a resource none too plentiful in
|
|
||||||
* this environment. Just don't set module parameters mpuio and
|
|
||||||
* mpuirq, and the MIDI port will be left uninitialized. You can
|
|
||||||
* still use the ICS2115 hosted MIDI interface which corresponds
|
|
||||||
* to the 9-pin D connector on the back of the card.
|
|
||||||
*
|
|
||||||
* endif ...WAVEFRONT...
|
|
||||||
*
|
|
||||||
* Supported chips are:
|
|
||||||
* CS4232
|
|
||||||
* CS4236
|
|
||||||
* CS4236B
|
|
||||||
*
|
|
||||||
* Note: You will need a PnP config setup to initialise some CS4232 boards
|
|
||||||
* anyway.
|
|
||||||
*
|
|
||||||
* Changes
|
|
||||||
* John Rood Added Bose Sound System Support.
|
|
||||||
* Toshio Spoor
|
|
||||||
* Alan Cox Modularisation, Basic cleanups.
|
|
||||||
* Paul Barton-Davis Separated MPU configuration, added
|
|
||||||
* Tropez+ (WaveFront) support
|
|
||||||
* Christoph Hellwig Adapted to module_init/module_exit,
|
|
||||||
* simple cleanups
|
|
||||||
* Arnaldo C. de Melo got rid of attach_uart401
|
|
||||||
* Bartlomiej Zolnierkiewicz
|
|
||||||
* Added some __init/__initdata/__exit
|
|
||||||
* Marcus Meissner Added ISA PnP support.
