I integrated this patch with our 2.6.24 kernel and it broke our APM-based battery monitor, which uses an ADC channel on the 9712. Support for this multi-function chip series seems to be in a few places; would it make sense to have one generic WM97xx driver in drivers/mfd and stack the codec, touchscreen, etc, drivers logically above (in their respective areas)? In my experience with the Wolfson series a change to the sound driver breaks touchscreen, a change to the touchscreen driver changes ADC readings, etc, so I wanted to open dialog on what the right direction may be as various Wolfson code starts making its way into the mainline.
Thanks, Pete MacKay
