Description
I did some tests for temp reading. I get the following readings from internal sensors in standby (no devices connected on WiFi) with a room temp of 20C:
phy0 2.4Ghz -> 68C
phy1 5Ghz -> 43C
On the SoC the reading by internal sensor is 45C.
The temperatures detected with a thermal scanner (my bet was 3-4C low) are:
on 2.4Ghz -> 37.1C
on 5Ghz -> 40.5C
On the Soc I get 45.5C.
It seems to me that the temp reading by the sensor on 2.4Ghz chip is not so correct.

Research direction
Start by reproducing the reported MT7915_phy0 temperature readings in standby and compare the 2.4 GHz, 5 GHz, and SoC internal-sensor values with the thermal-scanner measurements listed in the issue. Done means the 2.4 GHz reading discrepancy is explained and corrected, with the reported readings validated again.
