Sounds interesting. But right now I don't need to change any registers on the 
device directly, but rather specify that when new frontend parameters are 
set, register values XXX are used to program the frontend demodulator. I.e. 
the register values used by the driver need to be modified, so that the 
driver will use the new values instead of the default (as opposed to changing 
a register value, then having the driver write the default one again in the 
next frontend change).

I hope that made sense :-) 

Sorry if I misunderstood you.

In addition to the existing ones, or to replace them?

Sounds like a good idea, just wasn't sure if you'd be happy with the added 
complexity inside the kernel (i.e. parsers and pre/post processors). But I 
will add them :)
