- *
- * 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.
