I cherry-pick Miguel Aguilar CQ93VC and AIC3X support and I tested rec and play using arago_demo_image. Here you are what I've added to my 2.6.34-rc1 tree from for-2.6.35 branch of http://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound-2.6.git .

I have to verify the sound quality in recording and playback. I was trying to amplify SPP/SPN output, but it seems they have the same volume regulation of LINE OUT. Thank you very much, Raffaele.
