I believe the above snippet is not needed and is covered by the generic
ports.

Will or will not have any effect...

Please use get_maintainers.pl and send your patches to the right
lists/maintainers. DT patches only get reviewed if sent to DT list. So
please resend to the DT list. But before you do, I can tell this
binding hasn't been tested so fix all the warnings first.

Thanks Rob and Suzuki for the review.

I will fix the warning and update in next version.

+  TPDAs are responsible for packetization and timestamping of data sets
+  utilizing the MIPI STPv2 packet protocol. Pulling data sets from one or
+  more attached TPDM and pushing the resultant (packetized) data out a
+  master ATB interface. Performing an arbitrated ATB interleaving (funneling)
+  task for free-flowing data from TPDM (i.e. CMB and DSB data set flows).
