ARM: dts: sun7i: Correct USB regulators on pcDuino v3 Nano The LinkSprite pcDuino v3 Nano's two USB host ports are powered by a single RT9701GB regulator, which has its enable input tied to the A20's PD2 pin, pulled up to 3v3 via a 10k resistor. However, the script.bin that shipped with the device listed PH11 and PH3 as Vbus control pins for the two USB ports. Neither of these are actually connected to anything. Siarhei Siamashka spotted this problem while reviewing the other LinkSprite boards. This patch fixes it by only defining a single regulator, controlled by PD2. Testing shows that the USB ports are now (correctly) only powered up once the USB PHY driver is loaded.
