From c7d59e4b4e96dfa07dd5e4fef1897e54921a4560 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Fri, 9 Mar 2018 18:22:46 +0100 Subject: [PATCH] ARM: dts: exynos: Add audio clocks configuration for Snow Chromebook Currently the audio subsystem clocks are not configured properly on Snow and sound is not working. The MAX98095 CODEC is not getting its master clock on the MCLK pin connected to the SOC's CLKOUT GPIO. This patch adds CLKOUT and other clocks configuration so HDMI audio can also be supported.
