I'm not aware of any. And even if it were possible, I'm not sure putting 
tables with "version - feature-set" tables into the driver proper would be 
a very good idea. It used to be like that (or almost like that with 
dependencies on the chip-type) in other drivers (e.g., shdma) and we 
dropped it in favour of platform data.

Thanks
