Hi Jeff
Please see my new ali5451 driver (trident.c ) about read /write mixer regiser.
The ali_acquire_codec_access function do not acquire hardware semaphore. It is
audio driver request to write ac97 mixer register.
Please see ali5451 spec 's ACWR . I think that use Linux kernel semaphore (
spin_lock )is repeat because I do read / write Mixer regiser really till
after 48k Hz then codec clocking is 48k hz .In the ali_waitfor_stimertick
function ,You can see it.
Ali5451 (controller ) to codec connection by AC-link,a AC-link output frame
begin with a low to high transition of SYNC. SYNC is synchronous to rising edge
of BIT_CK. NEXT SYNC and SYNC is 48k Hz . So I think that transmit data is
right.
I attach file ( STIME ) :(See attached file: Stimer.doc)
