I tested the patches and got everything working with minor changes.
However, there seems to be some problem with PM, occasionally ASoC is
stuck with Standby mode (looking at dapm_widgets) when I start the
playback. Restarting the player brings the sound back. I'll carry out
some further investigation and get back to this.
My kernel is 2.6.27-rc3, and machine driver is adapted from
playpaq_wm8510.c to run on at91rm9200 board.
The SSC peripheral clock was disabled more often than it was enabled,
and that catched the bug trap in arch/arm/mach-at91/clock.c. I'm not
sure if this was the real problem, but it's the way I managed to solve
it.
