description:
The Temperature Sensor Unit (TSU) is an integrated thermal sensor that
monitors the chip temperature on the Renesas RZ/G3E SoC. The TSU provides
real-time temperature measurements for thermal management.

calibration trim values. The offset points to the first trim register
(OTPTSU1TRMVAL0), with the second trim register (OTPTSU1TRMVAL1) located
at offset + 4.
