The SpacemiT K1 SoC includes three USB ports: - One USB2.0 OTG port - One USB2.0 host-only port - One USB3.0 port with an integrated USB2.0 DRD interface Each of these ports is connected to a USB2.0 PHY responsible for USB2 transmission. This commit adds support for the SpacemiT K1 USB2.0 PHY, which is compliant with the USB 2.0 specification and supports both 8-bit 60MHz and 16-bit 30MHz parallel interfaces.
