[PATCH v2 net-next 10/10] mips: dts: ralink: mt7621: add GB-PC2 LEDs

From: Arınç ÜNAL <hidden>
Date: 2022-09-15 06:58:57
Also in: linux-arm-kernel, linux-devicetree, linux-mediatek, linux-mips, lkml
Subsystem: mips, ralink mt7621 mips architecture, the rest · Maintainers: Thomas Bogendoerfer, Chester A. Unal, Sergio Paracuellos, Linus Torvalds

Add the missing LEDs for GB-PC2. The ethblack-green, ethblue-green, power
and system LEDs weren't added previously, because they don't exist on the
device schematics. Tests on a GB-PC2 by me and Petr proved otherwise.

The i2c bus cannot be used on GB-PC2 as its pins are wired to LEDs instead,
and GB-PC1 does not use it. Therefore, do not enable it on both devices.
