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
|
