[PATCH v4 08/10] arm64: dts: qcom: talos: Enable CDSP cooling

From: Gaurav Kohli

Date: Fri Jul 03 2026 - 01:12:51 EST


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

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