Thanks for the Rant Rob, it finally got me moving :)

I am probably going to remove opp-microvolt-names property as well, if
we are going to use separate entries for all voltage ranges in OPP
node. i.e. two voltage ranges, slow and fast, like this:

                     regulator A       regulator B
opp-microvolt-slow = <tarA minA maxA>, <tarB minB maxB>;
opp-microvolt-fast = <tarA minA maxA>, <tarB minB maxB>;

Lets keep them as is for now, unless we have a real user.

That's the next thing I wanted to ask from Rob. We are surely not
going to use them and there are no users or kernel code to support
them today. Can we get rid of them from the DT ?
