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. > Comment applicable, if the USB PWRRDY signal is modelled as reset signal. There is no user for this patch. The first user is RZ/G3S and is there is no support yet. I think you should merge this patch with next one so that there is a user(RZ/G3S) for this patch.
