[PATCH 0/3] USB OTG on STM32F7 boards

[Amelie Delaunay]

This patchset adds support for Peripheral mode on stm32f746 by adding
dwc2 gadget fifo sizes and enables USB OTG HS in OTG (DRD) mode on
stm32746g-eval and stm32f769-disco. It possible to use OTG HS in
Peripheral or Host mode, depending on the USB connector.

[PATCH 1/3] ARM: dts: stm32: add gadget fifo sizes to usbotg_hs on stm32f746

[Amelie Delaunay]

USB OTG HS on STM32F746 can also be used as Peripheral (gadget), so
this patch adds DWC2 gadget mode fifo sizes bindings.

[PATCH 2/3] ARM: dts: stm32: select otg mode for usbotg_hs on stm32746g_eval

[Amelie Delaunay]

Configure USB OTG HS in OTG (DRD) mode on STM32746G_eval.
The USB connector used will determine the role of USB OTG controller.
