This is partially triggered by commit b97a31348379 ("usb: core: comply to PHY framework"), and partially due to how the Allwinner USB PHY driver handles phy_set_mode for non-OTG PHYs. This series fixes this in both places. Patch 1 makes phy-sun4i-usb accept PHY_MODE_USB_HOST for non-OTG PHYs. Patch 2 makes the usb core fall back to setting the mode PHY_MODE_USB_HOST if set_mode with PHY_MODE_USB_HOST_SS fails. If that fails then the failure path is the same as before. This should make it so existing USB 3.0 drivers are affected. The patches don't have any dependencies on each other, and could go in through separate branches. However this affects usability of USB input devices and Ethernet dongles, I'd rather they go in sooner than later.
