Hi it seems that 770 is also using aic23 alsa driver, original patches
added aic23 platform data driver code only to board-osk.c,
but this adds now a similar platform driver config also to board-nokia770.c.
I have only tested made a compile test for this one.Can somebody who is
building own kernels for 770 try to build, boot & "play it again sam"
with this?
The patch should apply on top of both to 2.6.16-omap2 branch and
linux-omap git head.
