4 Subject: [PATCH] ARM: dts: sun8i: fix USB Ethernet of Orange Pi R1
5
6 Orange Pi R1 uses a Realtek RTL8152B USB Ethernet chip, which is easily
7 seen on the board but not show in the schematics. A regulator for the
8 power of the RTL8152B chip is hidden, which uses the same pin with the
9 Wi-Fi regulator on the original Orange Pi Zero.
10
11 Add this regulator back to the device tree, and bind it to USB1.
