- 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).

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

Otherwise looks good to me.
