X-Git-Tag: v6.13-rc1~140^2~32^2~58
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a804c849ef89462ae6f7446d2ec9b919a3fb509d;p=thirdparty%2Fkernel%2Flinux.git

arm64: dts: rockchip: enable automatic fan control on Orange Pi 5+

This links the PWM fan on Orange Pi 5+ 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.

This is pretty much the same as '4a152231b050 ("arm64: dts: rockchip:
enable automatic fan control on Rock 5B")', except for the Orange Pi
5+ board.
