uwe a05702eaac Rework the driver to add EBus DMA support and improve APC DMA support. 
Audio-related stuff is left almost intact.

* support audiocs at ebus playback and capture
    tested on krups and u5 (thanks, martin)
* make first attempt at supporting audiocs at sbus capture
* nb: full-duplex is not tested
* while here, fix CSAUDIO_MONITOR_MUTE to be of CSAUDIO_MONITOR_CLASS
    i.e. outputs.monitor.mute -> monitor.monitor.mute

Ok by pk, eeh.

augustss 1339e88a86 Add a new optional method, dev_ioctl, to the audio hardware driver interface. 
It is called when an unrecognized ioctl() is performed on a device,
thus allowing ioctl()s that frob the hardware driver (like loading
microcode).

mrg 67cbdf5623 split sbus audiocs code up so we can share it with the ebus. XXX ebus DMA is probably different. 1999-06-05 14:29:10 +00:00
