Subject: [PATCH] arm64: dts: rockchip: enable automatic fan control on Rock 5B
This links the PWM fan on Radxa Rock 5B as an active cooling device
managed automatically by the thermal subsystem, with a target SoC
temperature of 65C and a minimum-spin interval from 55C to 65C to
ensure airflow when the system gets warm
