The K2 platforms have shown boot issues after switching to the DWC3 generic driver. Those are due to the fact that the USB domains are not turned off before booting linux and the phy were not properly initialized. Fixing it by improving the DWC3-generic driver and handling the USB power domain in the PHY driver.
Improvements to the DWC3 generic driver are: - core: read quirks properties from DT and apply the fixes. - add a new host driver that uses the DWC3 core (more generic than xhci-dwc3). This should enable most platforms to drop their own version of the xhci-driver to use the generic one instead.
This series also removes the now unused xhci-zynqmp driver and tries to better manage the Kconfig options related to DWC3 gadget/host mode selection.
This has been tested with K2 and DRA7 platforms (host and device modes). Travis build: https://travis-ci.org/jjhiblot/u-boot/builds/583080674
Changes in v4: - removed patches already merged (DWC3 fixes) - update more defconfigs (u200, sei510, rock64-rk332 and odroid-n2) - Fix the test of the USB_DWC3_GADGET option. IS_ENABLED() requires the whole option name including the 'CONFIG_' prefix
Changes in v3: - updated log message when defaulting to super speed
Changes in v2: Update commit log Select USB_GADGET_DUALSPEED if USB_DWC3_GADGET is selected
