[alsa-devel] [PATCH] ALSA: ASoC: TWL4030 codec - fix 256*Fs clock
According to TRM, 256*Fs clock output should be enabled when TWL4030 is in slave mode, not master. This allows sound to work on OMAP3 Pandora, which uses 256*Fs clock.

As we discussed on IRC you are correct! I apologize for not making this change when I resubmitted the patches last week. Somehow fell off my todo list.
