From 36fd56ab4d1d13adb9ced8592dc51e009240442d Mon Sep 17 00:00:00 2001 From: Konrad Dybcio Date: Tue, 2 Jan 2024 14:34:14 +0100 Subject: [PATCH] arm64: dts: qcom: sm8450: Hook up GPU cooling device In order to allow for throttling the GPU, hook up the cooling device to the respective thermal zones. Also, update the trip point label to be more telling, while at it.
