Fine to me and I can merge this patch once the binding for the 
"kirin970_hikey_usbhub" and "hi3670-dwc3" are ready.
Thanks!

Best Regards,
Wei

The compatible:
	"hisilicon,hi3670-dwc3"

was already merged upstream on this patch:

commit b68d9251561f33661e53dd618f1cafe7ec9ec3c2
Author:     Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
AuthorDate: Tue Sep 8 11:58:23 2020 +0200
Commit:     Felipe Balbi <balbi@kernel.org>
CommitDate: Thu Sep 24 11:56:01 2020 +0300

    usb: dwc3: simple: add support for Hikey 970
    
    This binding driver is needed for Hikey 970 to work,
    as otherwise a Serror is produced:

It follows the DWC3 schema, e. g.:

	Documentation/devicetree/bindings/usb/snps,dwc3.yaml

While double checking for "kirin970_hikey_usbhub", it sounds that
the dt-binding patch was not merged yet, and require further
discussions.

I'll re-start the upstream thread where this was discussed in
the past. I'll re-submit this patch once we finish such
discussions.

Thanks,
Mauro
