From 0b1f0e374404f70b77c0f79c6f16fdcf5484552b Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Wed, 27 Jul 2016 23:59:18 +0300 Subject: [PATCH] ARM: dts: r8a7794: add audio clocks Describe the external audio clocks (signals AUDIO_CLK[ABC]) required by the sound driver. Boards that provide audio clocks need to override the clock frequencies. This patch is based on the commit 0d3dbde84a45 ("ARM: shmobile: r8a7791: add audio clock on DTSI").
