[PATCH v2 8/8] arm64: dts: qcom: monaco: Enable CDSP cooling

From: Gaurav Kohli <hidden>
Date: 2026-01-27 15:58:21
Also in: linux-arm-msm, linux-pm, lkml
Subsystem: arm/qualcomm mailing list, arm/qualcomm support, the rest · Maintainers: Bjorn Andersson, Konrad Dybcio, Linus Torvalds

Unlike the CPU, the CDSP does not throttle its speed automatically
when it reaches high temperatures in monaco.

Set up CDSP cooling by throttling the cdsp when it reaches 105°C.
