[alsa-devel] [PATCH 03/17] arm/dt: Tegra: Enable audio on WM8903 boards, disable others

[Stephen Warren]

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.
