[PATCH v4 6/6] arm64: dts: qcom: glymur: Add GPU cooling

Tue May 12 12:21:23 PDT 2026
From: Manaf Meethalavalappu Pallikunhi <manaf.pallikunhi at oss.qualcomm.com>
The GPU does not throttle its speed automatically when it
reaches high temperatures. Set up GPU cooling by throttling
the GPU speed when it reaches 95°C.
