This WiFi AP is based on a MT7621 SoC with 128MiB RAM, 128MiB NAND,
a MT7603 2.4GHz WiFi and a MT7613 5GHz WiFi chips integrated on the board,
connected to the main SoC over PCIe.
The device uses NMBM over NAND, which is not currently supported in the
mainline, so NAND node is skipped in this revision.

Usually the led name would point to the component the LED is used for.
These are "generic" LEDs controlled from the userspace. The original firmware
uses GREEN for normal operations, RED for faults and BLUE for when WPS is
enabled. I'm not sure if there are any standard bindings that I can use here.
Looking at:
https://www.kernel.org/doc/html/latest/leds/leds-class.html#led-device-naming
You could use red:fault, green:power, and blue:wps. For node names,
led-fault, led-power, and led-wps.
