SubjectRe: [PATCH v5 1/2] dt-bindings: usb: qcom,dwc3: Convert USB DWC3 bindings
Hi Sandeep,

I would suggest to send v6 with the changes Rob and Stephen requested,
except for the 'assigned-clock-rate' constraints. A description instead
of the constraints is not ideal, but the constraints could be also be
added at a later time. Hopefully Rob can either ack with the description
or help to resolve the constraints issue.

Regards

Matthias
