[alsa-devel] [PATCH V2 4/4] ARM: dt: tegra: Enable audio on WM8903 boards, disable others
Stephen Warren

Thu Jan 12 00:09:57 CET 2012
Add complete bindings to instantiate and configure the codec and
top-level audio complex on all currently supported boards using the
Tegra+WM8903 audio driver.
On those boards, disable the I2S2 controller since it isn't used.
On boards not using the WM8903 codec, disable all the audio devices;
they can be re-enabled once the relevant codec and ASoC machine drivers
have been ported to device-tree.

v2: Adjusted DT content based on comments during review of ASoC-side
changes.
