Subject: [PATCH 04/10] arm64: dts: zx296718: set a better parent clock for I2S0
Date: Wed,  9 Aug 2017 14:30:45 +0800	[thread overview]
Message-ID: <1502260251-6316-5-git-send-email-shawnguo@kernel.org> (raw)
In-Reply-To: <1502260251-6316-1-git-send-email-shawnguo@kernel.org>

From: Shawn Guo <shawn.guo@linaro.org>

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.
