[PATCH] arm64: dts: qcom: sm6350: Add tsens thermal zones

From: Luca Weiss
Date: Wed Jan 24 2024 - 10:32:28 EST


Add the definitions for the various thermal zones found on the SM6350
SoC. Hooking up GPU and CPU cooling can limit the clock speeds there to
reduce the temperature again to good levels.

Most thermal zones only have one critical temperature configured at
125°C which can be mostly considered a placeholder until those zones can
be hooked up to cooling.
