[PATCH 2/3] arm64: dts: qcom: sc8280xp: camss: Add CCI definitions

[PATCH 2/3] arm64: dts: qcom: sc8280xp: camss: Add CCI definitions
Posted by Bryan O'Donoghue 1 year, 11 months ago 
sc8280xp has four Camera Control Interface (CCI) blocks which pinout to
two I2C master controllers for each CCI.

The CCI I2C pins are not muxed so we define them in the dtsi.

Is this _src really necessary? (the one above seems to be)

please refer to Documentation/devicetree/bindings/dts-coding-style.rst

The mA comments seem unnecessary

Also, please follow the style of existing pin nodes:

pins
function
drive-strength
bias-
