Subject: staging: mt7621-dts: do not use rgmii2_pins for ethernet on GB-PC1
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=56f1124a94699e18fde9421cfabed2312e7fc28e;p=linux.git

staging: mt7621-dts: do not use rgmii2_pins for ethernet on GB-PC1

GB-PC1 uses some of the rgmii2 pins (22 - 33) as GPIO. Therefore, the
rgmii2 bus cannot be used on this device.
Overwrite pinctrl-0 property under the ethernet node without rgmii2_pins on
the GB-PC1 devicetree.
