[PATCH v3 0/4] Add mt7986 thermal

[PATCH v3 0/4] Add mt7986 thermal

[Frank Wunderlich]

From: Frank Wunderlich <frank-w@public-files.de>

This series add thermal related devicetree-nodes and necessary
dt-bindings.

I left pwm-fan for r3 for now as i cannot test this completely due to
missing 2 pin-jack and 3v3 pwm-level which my fan cannot handle (starts
spinning at ~3V). Only checked voltage of pwm there.

changes in v3:
- efuse compatibles into one line

changes in v2:
- drop highest 2 trip points as they are not yet used
- leave already applied patches

this is based on Patch from openwrt. as my PWM-fan seems to need 5v pwm
signal and r3 only provides 3v3 on 3pin-socket it does not work for me.
