From: Sricharan Ramabadhran <quic_srichara@quicinc.com>

IPQ5018 has tsens V1.0 IP with 5 sensors, though 4 are in use.
There is no RPM, so tsens has to be manually enabled. Adding the tsens
and nvmem nodes and adding 4 thermal sensors (zones). The critical trip
temperature is set to 120'C with an action to reboot.

In addition, adding a cooling device to the CPU thermal zone which uses
CPU frequency scaling.
