Subject: [PATCH] pinctrl: armada-37xx: swap polarity on LED group
Date: Tue, 1 Oct 2019 10:51:38 -0500 [thread overview]
Message-ID: <20191001155154.99710-1-alpawi@amazon.com> (raw)
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.
Fixes: 87466ccd9401 ("pinctrl: armada-37xx: Add pin controller support for Armada 37xx")
