I'm now using the whole kernel from there and have applied my patches for the Ipaq214 to it. The Pxa2xx driver (with 3xx support) happily talks down the AC97 bus now.

I assume there were some changes in 2.6.25-rc4 mainline that aren't in the asoc-v2-dev yet. I will wait for the pxa3xx stuff to be merged into the mainline for this. What version of the mainline kernel is the latest asoc-v2-dev branch based on. (I'm still a little hazy on the git stuff I'm afraid). >> I want to get the touch screen working on my iPAQ 214, which uses the >> PXA310. It's a WM97xx chip on the AC97 interface.

Since I want both the wm97xx touchscreen and pxa3xx support, is there a simple way I can get the necessary changes in one applied to the other?
