Subject: [PATCH v3] arm64: dts: meson: add gpio-fan control to GS-King-X
Date: Fri, 10 Jun 2022 14:06:09 +0300 [thread overview]
Message-ID: <20220610110609.13533-1-f.kardame@manjaro.org> (raw)
GS-King-X has a single speed GPIO fan which is always-on by default. If we add controls for the fan and a trip point, the fan stays off most of the time, reducing background noise from the unit.
Signed-off-by: Furkan Kardame <f.kardame@manjaro.org>

Fixed speed-map indentation, aligned bracket, changed cooling-device and increased temperature to 70°C
