Subject[PATCH] ARM: dts: Enable HDMI audio support on exynos5800-peach-pi
Date
This patch adds new cpu, codec subnodes according to the updated
"google,snow-audio-max98091" DT bindings and the I2S clock tree
configuration so sound on the HDMI interface can be also supported.

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

NOTE:
I couldn't test this patch as I have no access to Peach-pi Chromebook.
I think it shoudn't be applied unless some acutally tests it.
