Log: MFC r344633-r344634, r344638 r344633: usb_nop_xceiv: Add support for this pseudo device This is a "fake" phy that handle regulator, clocks and reset gpio. Only clock and regulator is supported for now. Sponsored-by: Rubicon Communications, LCC ("Netgate") r344634: xhci_mv: Move the driver to generic_xhci Marvell XHCI is in fact generic-xhci, so move the driver and add the compatible string. While here, get and enable the phy if the dtb provide one. The xhci bindings state that phys should be in a 'phys' property but Marvell DTS uses 'usb-phy', only add support for 'usb-phy' for now.
