RK3568 has two USB 2.0 PHYs, and each PHY has two ports, the OTG port of PHY0 support OTG mode with charging detection function, they are similar to previous Rockchip SoCs.
However, there are three different designs for RK3568 USB 2.0 PHY. 1. RK3568 uses independent USB GRF module for each USB 2.0 PHY. 2. RK3568 accesses the registers of USB 2.0 PHY IP directly by APB. 3. The two ports of USB 2.0 PHY share one interrupt.
This patch only PHY1 with necessary attributes required to function USBPHY1 on U-Boot.
