[PATCH RFC v2 4/7] arm64: dts: allwinner: fix touchscreen reset GPIO polarity

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Quentin Schulz <quentin.schulz@xxxxxxxxxxxxxxxxxxxxx>

The reset line is active low for the Goodix touchscreen controller so
let's fix the polarity in the Device Tree node.
