Marek,
This series fixes the linux boot on the K2 platforms. without it the K2
platforms are broken. Can you give it a look please ?
Thanks,
JJ

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.
At the same time this series introduce a new uclass (UCLASS_NOP) to replace
usage of UCLASS_MISC in the USB wrapper because the MISC class now
automatically binds all the child devices.
Improvements to the DWC3 generic driver are:
- Fix it by switching to UCLASS_NOP
- 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).
