Subject: [PATCH v3 2/5] arm64: dts: rockchip: enable automatic active cooling on Rock 5B
Date: Thu, 29 Feb 2024 23:26:33 +0400 [thread overview]
Message-ID: <20240229-rk-dts-additions-v3-2-6afe8473a631@gmail.com> (raw)
In-Reply-To: <20240229-rk-dts-additions-v3-0-6afe8473a631@gmail.com>
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
