From 41ec0d50e29e14946ab135ef89a5571b5ec1455a Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Wed, 9 Aug 2017 14:30:45 +0800 Subject: arm64: dts: zx296718: set a better parent clock for I2S0 The default I2S0 parent clock AUDIO_24M can not be divided into required sample rate in some cases, for example when 48KHz is needed. Change the parent clock to AUDIO_99M which works for most sample rates.
