[PATCH 0/8] arm64: dts: phy: st: usb: Add STM32MP2 USB support

[Marek Vasut <marex@nabladev.com>]

Add USB support for STM32MP23xx/STM32MP25xx SoCs. This includes USB 2.0
FEMTO-PHY driver, DWC3 glue code and DT adjustments. Parts of this are
taken from ST downstream kernel fork, reduced, or rewritten, since not
all of the content there was useful and bits which might be missing and
are useful can be added later.

Unlike the downstream implementation, the DWC3 glue code is using plain
dwc3-generic-plat, the EHCI and OHCI controllers are instantiated as
plain generic controllers without any wrapper glue driver, and the USB2
PHY driver is simplified.

Both USB 2.0 Host controller and DWC3 super-speed controller are tested.
