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.simek@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
