[U-Boot] [PATCH v2 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.
This series applies on top of the master branch of USB tree.
It also also available on github: https://github.com/jjhiblot/u-boot/tree/dwc3_generic_v2

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'


Changes in v2:
- Updated commit log
- Fixed typo in thordown.c
- select DM_USB_DEV by default for zynqmp platforms

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
