Closed crawfxrd closed 1 month ago

crawfxrd commented 2 months ago

Enable PWRSW WDT 2 and use the default timeout of 10 seconds.

Allows forcing an EC reset in case it gets into an invalid state.

Models with IT8587E:

addw1
darp5
darp6
galp3-c
galp4
oryp5

It is impossible to use the PWRSW WDT on IT8587E boards. Clevo connected PWR_SW# to GPD0/RI# and not GPE4/PWRSW on all of them; GPE4/PWRSW is connected to DD_ON instead.
