mfd/Input: Changes for the new wm97xx MFD
The newly added proper driver model support for ac97 means we can now
have a real MFD for the wm97xx devices rather than the hacks that have
been used. Since they're mainly audio devices they're going via ASoC,
these are the other changes for cross tree merging.
Input: wm97xx: add new AC97 bus support
This adds support for the new AC97 bus code, which discovers the devices
rather than uses platform data.
As part of this discovery, it enables a multi-function device wm97xx,
which supports touchscreen, battery, ADC and an audio codec. This patch
adds the code to bind the touchscreen "cell" as the touchscreen driver.
This was tested on the pxa architecture with a pxa270 + wm9713 + the
mioa701 touchscreen.
