Subject: [PATCH 040/478] arm64: dts: rockchip: add thermal fan control to
|
||
|
|
rockpro64
|
||
|
|
|
||
|
|
The rockpro64 had a fan node since
|
||
|
|
commit 5882d65c1691 ("arm64: dts: rockchip: Add PWM fan for RockPro64")
|
||
|
|
however it was never tied into the thermal driver for automatic control.
|
||
|
|
|
||
|
|
Add the links to the thermal node to permit the kernel to handle this
|
||
|
|
automatically.
|
||
|
|
Borrowed from the (rk3399-khadas-edge.dtsi).
