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.
Michal Simek has tested this series:
" I have tested it on zcu100 with usb stick, usb to ethernet converter and
also dfu.
Tested-by: Michal Simek <michal.si...@xilinx.com>"
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 v4:
- rebased on latest U-Boot
- renamed DM_USB_DEV as DM_USB_GADGET
- Add a new commit to create a new UCLASS for USB gadget drivers
Changes in v3:
- fixes bug dwc3_setup_phy(): the phy arrays wasn't returned. This was
visible only when the device is removed.
- Stub the DWC3 PHY operations if CONFIG_IS_ENABLED(PHY) is false.
This fixes all build issues but one (evb-rk3328).
- Fix build issue with evb-rk3328 by enabling CONFIG_USB_DWC3. This has
little impact on the footprint and should not break the runtime as the
xhci-rockchip driver has its own probe function.
Nevertheless this was !!! NOT TESTED !!! by lack of hw
Changes in v2:
- Updated commit log
- Fixed typo in thordown.c
- select DM_USB_DEV by default for zynqmp platforms
