[PATCH v4 2/4] usb: dwc3: of-simple: Add compatible for rk3328

[lindsey.stanpoor]

From: Cameron Nemo <cnemo@tutanota.com>

Add a compatible to be hooked into by the Rockchip rk3328 device tree.

The rk3399 compatible cannot be reused because the rk3328 SoCs may
require a specialized driver in the future, and old device trees must
remain compatible with newer kernels.

[PATCH v4 3/4] arm64: dts: rockchip: rk3328 usb3 controller node

[lindsey.stanpoor]

From: Cameron Nemo <cnemo@tutanota.com>

RK3328 SoCs have one USB 3.0 OTG controller which uses DWC_USB3
core's general architecture. It can act as static xHCI host
controller, static device controller, USB 3.0/2.0 OTG basing
on ID of USB3.0 PHY.

Hi all,

Wanted to give this patch submission a gentle ping.

Rob Herring acked the documentation changes, but I have not heard
anything
from the USB or Rockchip maintainers. This patchset would facilitate USB3
support for Rockchip rk3328 devices like the Pine Rock64.

If there is anything I can do to help move this along, please let me know.

Thank you,
Cameron

Sorry, it had fallen through the cracks. It's now in my testing/next.

Following up on this. Will this move out of your testing/next?

The binding changes are likely stale now that the dwc3 binding has been
converted to YAML. See Greg's USB tree.

Also the DT changes should go through the arm-soc tree separately, so
we can stack on additional changes enabling USB3 on other boards.
