Subject: [PATCH 3/4] arm64: dts: rockchip: enable temperature driven fan control on Rock 5B
Date: Thu, 25 Jan 2024 00:30:06 +0400 [thread overview]
Message-ID: <20240125-rk-dts-additions-v1-3-5879275db36f@gmail.com> (raw)
In-Reply-To: <20240125-rk-dts-additions-v1-0-5879275db36f@gmail.com>
This enables thermal monitoring on Radxa Rock 5B and links the PWM
fan as an active cooling device managed automatically by the thermal
subsystem, with a target SoC temperature of 55C
