Subject: arm64: dts: amlogic: meson-sm1-odroid-hc4: fix active fan thermal
|
|
trip
|
|
|
|
Add an active trip tied to the on-board fan cooling device, which is better
|
|
than describing it along the passive cooling maps.
|
|
|
|
Fixes: 33b14f663df8 ("arm64: dts: meson: add initial device-tree for ODROID-HC4")
