[alsa-devel] [PATCH RFC 0/3] WM97xx AC97 GPIO support

Here's 3 patches which implement simple AC97 GPIO support to the WM97xx touch
drivers and the Alchemy (au1x) AC97 ASoC implementation.

Tested on Au1200 hardware with a WM9712 codec:  According to Mark Brown the
WM9712 only sets GPIOs when data is sent through slot 12, which prompted me
to implement this.

  sound: ac97: Add GPIO manipulation hooks
  input: wm97xx: set GPIOs with AC97 GPIO busops if implemented
  sound: asoc: au1x: implement AC97 GPIO access
