Paul Kocialkowski 0d5824cbc9 phy: sun4i-usb: Fix PHY0 routing and passby configuration for MUSB ... Recent Allwinner platforms (starting with the H3) only use the MUSB controller for peripheral mode and use HCI for host mode. As a result, extra steps need to be taken to properly route USB signals to one or the other. More precisely, the following is required: * Routing the pins to either HCI/MUSB (controlled by PHY); * Enabling USB PHY passby in HCI mode (controlled by PMU). The current code will enable passby for each PHY and reroute PHY0 to MUSB, which is inconsistent and results in broken USB peripheral support. Passby on PHY0 must only be enabled when we want to use HCI. Since host/device mode detection is not available from the PHY code and because U-Boot does not support changing the mode dynamically anyway, we can just mux the controller to MUSB if it is enabled and mux it to HCI otherwise. This fixes USB peripheral support for platforms with PHY0 dual-route, especially H3/H5 and V3s.
