Subject: [PATCH v3] arm64: dts: rockchip: add thermal fan control to rockpro64
Date: Fri, 30 Jul 2021 11:17:27 -0400	[thread overview]
Message-ID: <20210730151727.729822-1-pgwipeout@gmail.com> (raw)

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).

Signed-off-by: Peter Geis <pgwipeout@gmail.com>

Changelog:
v3:
Removed the gpu nodes to prevent in-fighting (thanks Robin!)

v2:
Adjusted fan setpoints for less noise
