The STM32F7 MCU family embeds two DWC2 USB OTG cores. One core is USB
OTG FS and the other is USB OTG HS. The USB FS core only works with its
internal phy whilst the USB HS core can work in HS with external ULPI phy
or in FS/LS with the on-chip FS phy.

Patches 3 to 7 applied on stm32-dt-for-v4.15 branch.
Currently USB stack is not enabled by default (and will not be). If you
plan to use USB don't forget to create a reserved memory region for DMA
pool (as DMA and caches are not friends on cortex-M7) in devicetree.
Reserved memory region for DMA pool support will be added in stm32F7 and
stm32H7 devicetree as soon series "ARM: NOMMU: MPU updates" from
Vladimir Murzin will be merged.
Regards
Alex
