I'm not too sure about this one. There's basically two ways to look at
this: you described the first one, and the second one would be to
treat it as we do for the compatibles: the IP was introduced on one
SoC family, and then got used on some other ones.

Trying to always match the one you have however have a quite big
maintainance cost, as can be shown by your patch: you always have to
adapt comments, function names, defines, etc. This creates a lot of
useless churns (ie, non-functional changes) in the drivers, that need
to be written in the first place, and then reviewed.

It's just not worth it.

Maxime
