I'm no device tree expert but these look like config options rather than
HW
description. They also don't appear to be documented in the next patch.  

The poll_freq are part of the msgdma prefetcher IP, whereby it
specifies the frequency of descriptor polling operation. I can add
the poll_freq description in the next patch.

Is the value decided at the time of synthesis or can the driver choose 
the value it wants?

It is not controlled at synthesis, this parameter should likely not be a
devicetree parameter, perhaps just make it a module parameter with a default
value.
