THS0 has only one temperature sensor, which is located in the DRAM controller. THS1 does have 4 sensors: ths1_0 - "big" cores ths1_1 - "little" cores ths1_2 - gpu ths1_3 - npu Add the thermal sensor configuration and the thermal zones. Trips temperature, polling-delay and sustainable-power parameters are derived from the manufacturer's BSP.
