[PATCH] arm64: dts: rockchip: Add idle cooling devices

From: Daniel Lezcano
Date: Fri Oct 01 2021 - 12:17:43 EST


The thermal framework accepts now the cpu idle cooling device as an
alternative when the cpufreq cooling device fails.

Add the node in the DT so the cooling devices will be present and the
platforms can extend the thermal zone definition to add them.
