Subject: [PATCH v4 5/6] arm64: dts: allwinner: a64: Add pinmux setting for CSI MCLK on PE1
Date:   Tue, 18 Dec 2018 17:03:19 +0530

Some camera modules have the SoC feeding a master clock to the sensor
instead of having a standalone crystal. This clock signal is generated
from the clock control unit and output from the CSI MCLK function of
pin PE1.

Add a pinmux setting for it for camera sensors to reference.
