Subject: [PATCH 6/8] arm64: dts: meson: g12b: odroid-n2: add fan as cooling
|

device

Add the GPIO fan as a cooling device for the CPU thermal zone. Since we
|
|
have only full fan speed available with this, set the tripping point to
|
|
65°C which is the highest tripping point which Hardkernel used in their
|
|
downstream kernel.
