[PATCH v2 1/4] dt-bindings: usb: add DT binding for RK3328 dwc3 controller

[PATCH v2 1/4] dt-bindings: usb: add DT binding for RK3328 dwc3 controller

[Heiko Stuebner]

From: William Wu <william.wu-TNX95d0MmH7DzftRWevZcw@public.gmane.org>

Adds the device tree bindings description for RK3328 and
compatible USB DWC3 controller.

changes in v2:
- add Rob's Ack

Ideally usb maintainers would pick up this patch to the binding
document and I'll take the devicetree changes after that.

But if so desired, I can also pick up the binding change myself
but would need an Ack for that.

just realized, the last version from august was actually v3, so this
should be v4, not v2 ... sorry about that.

do you want to pick this patch with only the small dt-binding
change or Ack it for me to pick up together with the actual
devicetree changes in the other patches?


Thanks
