Subject: [PATCH 1/2] arm64: dts: allwinner: a64: Add pinmux setting for CSI MCLK on PE1
Date: Thu, 18 Apr 2019 14:08:12 +0530 [thread overview]
Message-ID: <20190418083813.11776-1-jagan@amarulasolutions.com> (raw)
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.
