[U-Boot] [PATCH v1 0/7] Improvements for the dwc3_generic driver

[Jean-Jacques Hiblot]

This series aims at bringing improvements to the dwc3_generic driver so
that it can be used by most of the platforms using the dwc3 controller.

I tested this on with DRA7 and AM57x platforms for both Peripheral and Host
operations. The code to enable DM USB host & dev support for those
platforms will be submitted in a separate series.

Enhancements:
- use separate Kconfig option for DM USB Periphal and DM USB Host. This
allow platforms to keep their non-DM USB peripheral code and use the DM
USB host.
- fixes the bind/probe confusion in dwc3_generic. The probe is done when
the USB device is first needed.
- handles PHYs when in the peripheral mode. The code to handle the PHYs is
shared with the host side
- handles clock and reset
- bind host controller to the more generic driver 'xhci-dwc3'



Jean-Jacques Hiblot (7):
  usb: gadget: Do not call board_usb_xxx() directly in USB gadget
    drivers
  usb: introduce a separate config option for DM USB device
  usb: udc: implement DM versions of
    usb_gadget_initialize()/_release()/_handle_interrupt()
  dwc3_generic: do not probe the USB device driver when it's bound
  dwc3: move phy operation to core.c
  dwc3-generic: Handle the PHYs, the clocks and the reset lines
  dwc3-generic: Add select_dr_mode operation
