Ok. I took a long look at this today. I rewrote a bunch of stuff.
Let me know if anything looks wrong. I'm not really interested in
having a type template design that causes us to jump through one
clk op to another set of them. I'd rather keep it flatter. I also
kept around the macros for the offsets and had it use a register
map in each struct instead. Yes, we have to go modify the PLL
types to point to the right register offset, but really that's
fine and I don't really care. We could have a default fallback
when the reg pointer is NULL, but I'm not sure that is useful.
The alternative is to make a bunch of new ops structures that
passes it down into the final functions but that seemed like more
work for the handful of PLLs we have to worry about. You seem to
agree here. All told, it got cut down by 100 lines so the patches
got smaller.
