[PATCH v5 4/5] arm64: dts: mediatek: mt8192: Add thermal nodes and thermal zones
Bernhard Rosenkränzer

Tue Oct 17 12:05:44 PDT 2023
From: Balsam CHIHI <bchihi at baylibre.com>
Add thermal nodes and thermal zones for the mt8192.
The mt8192 SoC has several hotspots around the CPUs.
Specify the targeted temperature threshold to apply the mitigation
and define the associated cooling devices.
