usb: dwc3: disable USB core PHY management
The dwc3 driver manages its PHYs itself so the USB core PHY management needs to be disabled. Use the struct xhci_plat_priv hack added by commits46034a999c
("usb: host: xhci-plat: add platform data support") andf768e71891
("usb: host: xhci-plat: add priv quirk for skip PHY initialization") to propagate the setting for now. Fixes:4e88d4c083
("usb: add a flag to skip PHY initialization to struct usb_hcd") Fixes:178a0bce05
("usb: core: hcd: integrate the PHY wrapper into the HCD core") Tested-by: Matthias Kaehlcke <mka@chromium.org> Cc: stable <stable@kernel.org> Reviewed-by: Matthias Kaehlcke <mka@chromium.org> Signed-off-by: Johan Hovold <johan+linaro@kernel.org> Link: https://lore.kernel.org/r/20220825131836.19769-1-johan+linaro@kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
