Subject: Re: [PATCH v1 1/2] dt-binding: ptp: add bindings document for dte
 based ptp clock

Hi David, Rob,
I will address all of Rob's comments below.

Since a part of the patch was applied to 'net-next', would you like me to
send a new patch (based on the applied one), or a 'V2' of this patch ?

Thanks
Arun
