Subject: arm64: dts: mt7986: change cooling trips
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1fcda8ceb014aafd56f10b33e0077c93b5dd45d1;p=linux.git

arm64: dts: mt7986: change cooling trips

Add Critical and hot trips for emergency system shutdown and limiting
system load.

Change passive trip to active to make sure fan is activated on the
lowest trip.
