[PATCH v2 0/4] usb: dwc2: add optional clock used on stm32mp15

[Fabrice Gasnier]

This series introduces an optional utmi clock that is used on stm32mp15,
in particular when using integrated full-speed PHY, managed by GGPIO
register.
A pre-cursor change improves error handling in the platform code.
