The Renesas RZ/V2N SoC includes a Thermal Sensor Unit (TSU) block designed
to measure the junction temperature. The device provides real-time
temperature measurements for thermal management, utilizing two dedicated
channels for temperature sensing:
- TSU0, which is located near the DRP-AI block
- TSU1, which is located near the CPU and DRP-AI block
Since TSU1 is physically closer the CPU and the highest temperature
spot, it is used for CPU throttling through a passive trip and cooling
map. TSU0 is configured only with a critical trip.
Add TSU nodes along with thermal zones and keep them enabled in the SoC
DTSI.
