[ALSA] AC97 wm9713 support
AC97 Codec
This patch series adds support for the WM9713/WM9714 family of AC97
codecs. This family is different from 'standard' AC97 codecs in that the
default codec power state is 'off'. i.e. performing a register reset
will power the device down.
This patch also adds better support for larger single/double channel
enumerated mixer types.
