[alsa-devel] [PATCH V4 0/5] AC97 driver for mpc5200

[Jon Smirl]

Version 4. Changed timeouts to use relax_cpu() instead of udelay(). Fixed locking to lock bestcomm instead of
registers. Code reorg as requested in the various comments. Removed sysfs over/underrun reporting. Removed 
reset retries. Removing the retries makes the driver fail to load about 5% of the time. An oscilliscope is 
needed to figure out what is going on with failed resets. Both pcm030 and Efika ocasionally fail to reset 
and they use different codec chips.
