mediatek: re-add dropped properties on BPi-R3
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. Fixes: 7a0ec00 ("mediatek: sync MT7986 device trees with upstream") Signed-off-by: Daniel Golle <daniel@makrotopia.org>

| Subject: [PATCH 20/22] arm64: dts: mt7986: define 3W max power to both SFP on | ||
| BPI-R3 | ||
|
|
||
| All SFP power supplies are connected to the system VDD33 which is 3v3/8A. | ||
| Set 3A per SFP slot to allow SFPs work which need more power than the | ||
| default 1W. | ||

|
|
||
| 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. | ||
