Subject: [PATCHv3] arm64: dts: meson: Enable active coling using gpio-fan on Odroid N2/N2+
Date: Sat, 22 Oct 2022 08:47:34 +0000	[thread overview]
Message-ID: <20221022084737.1028-1-linux.amoon@gmail.com> (raw)

Odroid N2/N2+ support active cooling via gpio-fan controller.
Add fan controls and tip point for cpu and ddr thermal sensor
on this boards. Drop bias-disable from set pwm_ao_d_10 the pin
as to allow transition from say pull-up to pull-down for on/off
of the fan.

v2: changes tip name cpu-active --> ddr-active
v3: drop bias-disable for pwm_ao_d_10 pine.
