Subject: [PATCH] pinctrl: armada-37xx: swap polarity on LED group
Git-commit: b835d6953009dc350d61402a854b5a7178d8c615
Patch-mainline: v5.4-rc5
References: git-fixes bnc#1151927 5.3.8
The configuration registers for the LED group have inverted
polarity, which puts the GPIO into open-drain state when used in
GPIO mode. Switch to '0' for GPIO and '1' for LED modes.
