[alsa-devel] [PATCH] ASoC: pandora: Add APLL supply to fix audio output

Pandora's external DAC is using 256*Fs output from the TWL4030
codec, and TWL4030 needs to have APLL enabled for it's 256*Fs
output to function.

I noticed this a bit late because TWL4030 codec used to have APLL
enable hardcoded until that was clean up by not-so-old patch.
Would be nice to see this in next -rc, as without this audio
won't work completely on pandora (again)..
