What's with the redundant namespacing?

Have we not, as a community, realised that we do not need to namespace
properties which are only present under
a single binding or node, or even those that aren't? This mess started
with the regulator bindings and it's never
stopped. What are we at now, 25 years of device trees, 10 years of FDT on Arm?

Notwithstanding the complete waste of rodata in the kernel image for
matching (& increased time to compare), why
wouldn't you consider why "bank-offset" for your node be any different
than a common property for any other node?

And if you need to describe register offsets... why aren't you able to
use the reg property?

Ta,
Matt
