[alsa-devel] PCM3008 ALSA Soc driver and Lyrtech SFFSDR board audio support (v2)

Reworked and splitted patch based on Mark Brown comments.

Mark, thank-you for your comments. I implemented almost all of your suggestions, except for the de-emphasis control because I don't really know how I can export (and test) that interface. Like you said, maybe we or someone else can do it later.
