Laurent, Thanks. That was my bad.
I have checked up both the code base LSP 2.10 and Git version of the driver and both has support for poll/select. They call videobuf_poll_stream(). May be what is referenced here is LSP version older than this. Murali Karicheri Software Design Engineer Texas Instruments Inc.
