[PATCH v8 2/4] arm64: dts: qcom: lemans: Add GPU cooling
From: Akhil P Oommen
Date: Wed Nov 05 2025 - 12:12:01 EST
From: Gaurav Kohli <quic_gkohli@xxxxxxxxxxx>
Unlike the CPU, the GPU does not throttle its speed automatically when it
reaches high temperatures.
Set up GPU cooling by throttling the GPU speed
when reaching 105°C.
