Yes, I also wondered about going the opposite way but then thought that is more natural to look for clock bindings under bindings/clock and for regulators drivers under bindings/regulator...

...but I don't have a strong opinion and can do the other way if folks are more fond with that single file approach.
What I think is that it should be consistent, either everything is in mfd for all PMICs or everything is split.
The max77686 for example has a somehow arbitrary split since the clocks are in another file but the regulators are in the same mfd binding doc.
