[PATCH v5 6/9] arm64: dts: qcom: lemans: Enable CDSP cooling
From: Gaurav Kohli
Date: Tue Jul 21 2026 - 02:31:18 EST
Unlike the CPU, the CDSP does not throttle its speed automatically
when it reaches high temperatures in lemans.
Set up CDSP cooling for both instances by throttling the cdsp, when
it reaches 105°C.
