[Apparently I first replied to a version sent privately and not to the
list.]
I'm afraid it's not enough to keep the codebase consistent.
Like, what's the point of changing enum pipe pipe to int idx, if you're
still going to use it with functions and macros that are named after
pipe?
I think Ville mentioned we should be talking about crtcs.
I know it's not an easy task, but the whole point here is not to make
quick and dirty changes, but to ensure we still have a readable codebase
and there is no confusion between what is a pipe and what is a crtc (or
crtc index).
BR,
Jani.
