Subject: [PATCH 3/4] arm64: dts: rockchip: Add cooling map / trip points for RK356x' GPU
Date: Fri, 26 Nov 2021 16:17:28 +0100 [thread overview]
Message-ID: <20211126151729.1026566-4-knaerzche@gmail.com> (raw)
In-Reply-To: <20211126151729.1026566-1-knaerzche@gmail.com>
RK356x SoCs have a second thermal sensor for the GPU:
This adds the cooling map / trip points for it to make use of it's
contribution as a cooling device.
