While mainlining Rock Pi 4 its leds were probably overlooked in the dts.
|
|
Power led is not usable in currently available board revisions <= 1.4
|
|
and is disabled in dts to not confuse users who would like to fiddle with it.
|
|
|
|
It could possibly be made controllable by its gpio with the help
|
|
of soldering iron, steady hands, patience (SMD0402) and additional overlay
|
|
to enable the led and its gpio pin in device tree.
