    phy-sun4i-usb: Add support for peripheral-only mode · b33ecca8
    Hans de Goede authored
    Use the new of_usb_get_dr_mode_by_phy() function to get the dr_mode
    from the musb controller node instead of assuming that having an id_det
    gpio means otg mode, and not having one means host mode.
    
    Implement peripheral-only mode by adding a sun4i_usb_phy0_get_id_det
    helper which looks at the dr_mode, always registering our extcon and
    always monitoring vbus.
    
    If dr_mode is not specified in the dts, do not register phy0 as we then
    do not know how to treat it. This is actually a good thing as this means
    we will not be registering phy0 on devices where the otg controller is
    not enabled in the devicetree.
