1. You should send some kernel mode TDM clients. Without those the framework
   is pretty useless.
[Sandeep] We do have a test client but not good enough to be pushed in open source, should we add it to documentation?? 

2. It would probably make sense to Cc: netdev and serial. There may be
   some kernel client network integration from the start.
[Sandeep] Ok. 

3. Where is the userspace configuration interface ?
[Sandeep] TDM framework right now supports only kernel mode clients. It has been tested with the client module that I mentioned above. Both the framework and test client are a part of Freescale BSP.

[Sandeep] Please try below mentioned link. The above one is Freescale's internal mirror of:

$ git clone git://
