When USB area is not used the PWRRDY bit of the SYS_USB_PWRRDY register need to be set. This register is in the SYSC controller address space and the assert/de-assert of the signal handled by SYSC_USB_PWRRDY was implemented as a reset signal. The USB modules available on the RZ/G3S SoC that need this bit set are: - USB ch0 (supporting host and peripheral mode) - USB ch2 (supporting host mode) - USBPHY control As the USBPHY control is the root device for all the other USB channels (USB ch0, USB ch1) add support to set the PWRRDY for the USB area when initializing the USBPHY control. As this is done though reset signals get the reset array in the USBPHY control driver.
