Okay reviewing this after the other Xilinx driver with very similar name, I
am very concerned about code duplication. Both codes seems to be pretty much
copy paste and some modifications for IP. In Linux kernel we reuse!

Please create common lib for Xilinx drivers to use and
have HW diff is two drivers, or manage those with different driver ops

Pls justify why we should have two drivers. Looking at code makes me think
