[alsa-devel] [PATCH] ASoC: wm8994: Add clock bindings to the device tree

From: Mark Brown <broonie at linaro.org>

Due to the variable availability of the clock API there is no code in the
driver to use these at present, for the time being the machine drivers
will need to handle requesting clocks.
