Eliot Blennerhassett f3d145aac9 ALSA: asihpi: MMAP for non-busmaster cards
Allow older non DMA capable cards to use MMAP by
emulating the DMA using read and write functions,
and getting rid of copy & silence callbacks that
were used only by older cards.

Eliot Blennerhassett 0b7ce9e2bd ALSA: asihpi: Handle playback drained status better
Use the card drained status reporting for playback,
but allow it to persist for a few timer cycles before
signalling XRUN, to allow card to recover by itself.

Eliot Blennerhassett 550ac6ba4e ALSA: snd-asihpi: Control naming
Clock source is neither capture nor playback,
so change 'Capture Clock' to 'Clock'.
Add spaces to control name string for consistency,
always 'PCM 0' , never 'PCM0'

Eliot Blennerhassett b2e65c8e91 ALSA: asihpi - Update verbose debug print macros
Replace local VPRINTK1 with snd_printdd.
Create local snd_printddd instead of VPRINTK2 for most verbose debug.
In most cases let snd_printk supply default level for messages.

Eliot Blennerhassett 26aebef420 ALSA: asihpi - Improve non-busmaster adapter operation
Make playback silence callback a no-op, card automatically outputs
silence when written data runs out.
Increasing update interval and thus minimum period avoids xrun on startup
or because of timer jitter.

Eliot Blennerhassett 7bf76c33e9 ALSA: asihpi - Support single-rate no-SRC cards
Cards without settable local samplerate and without SRC
still must have a valid samplerate.
This fixed rate is determined by reading the current rate for the card.

Eliot Blennerhassett e64b1a28c5 ALSA: asihpi - Rewrite PCM timer function. Update control names.
Reported samples_played from card may be inaccurate, so don't use it.
Update control names to be closer to alsa standard practice.
Also fixed some accidentally lowercased strings.

[Removed adriver.h inclusion for external module builds by tiwai]
