Add USB controller and USB PHY controller nodes to Exynos7885 SoC DTSI The SoC theoretically supports USB3 SuperSpeed, but is not implemented in any known device. The vendor kernel also stubs out USB3 functions, so we do not support it. It is though, perfectly capable of USB 2.0 high-speed mode, both as host and device.
