This is actually part of the same thing. These are prep patches for moving
VLV/CHV into the dpll infrastructure. But fair enough.


But I have to disagree this would create an even bigger mess. There is so much
code in intel_display.c that most static functions there are the equivalent of
an undocumented non-static function elsewhere. And since they are in the same
pile of 400+ functions, it is not obvious the documentation is missing. So I'd
claim splitting code out of intel_display.c, even if without documentation, is
an improvement.

With the current rules we transfer the burden of writing documentation from the
person that made intel_display.c longer to the one trying to make it smaller.
Maybe we should have an exception that everything in intel_display.c needs
kerneldoc?
