Anyone knows or figured out how to use devicetree overlays with U-Boot? Or any other method which can be used to add extra nodes to the device tree without recompiling OpenWRT?
The big picture is simple, I would like to create a 3D printable chassis for myself which looks like any other off-the-shelf desktop router. Most of this devices have some or more front panel LEDs. Some signals already on the board (and can be hijacked) but for the missing ones, I need a couple new device nodes with “gpio-leds” type to attach triggers to it.
