[PATCH 01/10] arm64: dts: zx296718: add VGA device support

[Shawn Guo]

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

It adds VGA device in zx296718.dtsi, so that boards with VGA connector
can enable the support by changing 'status' in board DTS file.

[PATCH 04/10] arm64: dts: zx296718: set a better parent clock for I2S0

[Shawn Guo]

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.
