Subject: arm64: dts: qcom: sm8750: Enable TSENS and thermal zones
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=746ad6b00c4dcda768253f063bfe1c6cbf338444;p=thirdparty%2Fkernel%2Fstable.git

arm64: dts: qcom: sm8750: Enable TSENS and thermal zones

The sm8750 includes four TSENS instances, with a total of 47 thermal
sensors distributed across various locations on the SoC.

The TSENS max/reset threshold is configured to 130°C in the hardware.
Enable all TSENS instances, and define the thermal zones with a hot trip
at 120°C and critical trip at 125°C.
