Subject[PATCH v2 4/4] ARM: dts: Enable HDMI audio on Snow Chromebook
Date
This patch adds new cpu, codec subnodes according to the updated
"google,snow-audio-max98095" DT bindings and the I2S clock tree
configuration so sound on the HDMI interface can also be supported.

Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com>

Changes since v2:
- changed order of codec phandles in codec/cpu-dai property
to match the DT bindings documentation.
