Convert this from the old style text based binding to the new DT schema
style. This will make adding the MT6366 portion easier.

The examples have been trimmed down considerably, and the remaining
entries now match what is seen in actual device trees.

The original submitter seems to have left MediaTek, so instead the
submitter and maintainer for the MT6366 binding is listed.

mt6397?

Both cases look a bit confusing.

There's only two regulator binding header files, mt6397 and mt6360.
They seem to correspond to the two classes of PMICs that MediaTek has.
I believe the two header files and thus the macros are meant to be
shared?

MT6397 and co refer to their AP PMICs, i.e. PMICs that are companion
chips to the SoC and provide most of the power rails a system needs,
along with things like RTC, audio codecs, etc.. The MT6358 and MT6366
belong to this class.

MT6360 and possibly others refer to their charger PMICs, which integrate
a battery charger, USB type-C PD stuff, LED drivers, and a handful of
regulators.

Defines have specific model name, so they do not look like meant to be
shared. If all the values of the binding match, they can be shared, but
then this should be mentioned in the binding plus it should be used in
the driver. I don't see your driver patches add include of this header.

Indeed. AFAICT the original raw values 0 and 1 just map directly to the
register bitfield values. And those are common across the series of PMICs.
I'll look into cleaning it up.
