So, you folks at Greensocs had a series a couple of years ago to try
to add clocktree support (which included handling things like guests
configuring clock rates, some clocks being "downstream" of others, and
so on). It didn't make it into mainline, though it did get a fair amount
of design/code review. How does this approach fit into / compare with
that ?
