[ALSA] AZT3328 driver update
Modules: AZT3328 driver this is now an even much more reworked patch (#3) for my azt3328.c ALSA driver. IOW I spent another 4 evenings to get the sequencer timer to work properly (my head is still hurting) and do lots of other cleanups. Note that despite the extensive sequencer timer additions, the driver object is still only 2kB bigger than the previous version, due to those many optimizations... Changes in version #3: - fully working ALSA sequencer timer support for the card's 1024000Hz DirectX timer (downscaling adjustable via seqtimer_scaling module param) - an insane amount of code optimizations - many, many cleanups Changes in version #2: - FOUND the 1us DirectX timer area (yay!), made the code respect it properly - renamed some 'weird' mixer control names according to ControlNames.txt - cleanup unneeded debug messages, reformatting - improved I/O register documentation - constified many more structs Changes in version #1: - improves/fixes some fatal playback/recording interaction - improves IRQ handler performance (and actually fixes some weird code) - coalesces some I/O accesses - slightly improves I/O interface documentation - improves/fixes logging - defines out some less important debug code - constifies some data Signed-off-by: Andreas Mohr <andi@lisas.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
