From fb18c893816b37c907c1c0883b92e19dcad58c97 Mon Sep 17 00:00:00 2001 From: Konrad Dybcio Date: Tue, 2 Jan 2024 14:34:12 +0100 Subject: [PATCH] arm64: dts: qcom: sm8250: 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.
