Unfortunately some device tree properties have slipped under the table
when switching from our downstream device tree.
Bring back 3W power for SFP cages and restore thermal trip points to
make sense again.

Subject: [PATCH 21/22] 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.
|
|
|

Fixes: 1f5be05132f3 ("arm64: dts: mt7986: add thermal-zones")
