No worries about asking - that's totally legit!

Happy to see that you're going serious with the upstreaming of the Dimensity 7300!
I admit I'd be proud to finally see some modern MediaTek smartphone upstream, as
there is practically none (well, apart from some old-old-old stuff that I added
and - ugh - only partially) and I don't think that those deserve to become e-waste
"just like that".

Those regulators are required for the MediaTek Kompanio Ultra (MT8196) SoC, and yes
I plan to respin this series as soon as possible.

I should also be trying to upstream the MT6685 RTC in the future (not clkbuf, most
probably, as that doesn't seem to be actually needed for anything meaningful).

As for MT6319 and MT6369, I currently have no plans for upstreaming those, at least
for now.

Besides, does the Dimensity 7300 also use SPMI 2.0?
In case you missed it:

Also - if this can help you in any way, we (as Collabora) are performing all of the
upstreaming work publicly: the commits that aren't "exactly ready yet" (but working
anyway) are of course available to everyone... and also some WIP things.

This includes, for example, the SCMI TinySYS Protocol (which probably D7300 also
uses) and DVFSRC v4 code, other than devicetrees that are close to upstream for the
MT8196 platform - of which, some new style nodes should apply to your SoC (not in
a 1:1 copy-paste fashion, but you get the point, I guess).

Check it out:

Beware that we have multiple branches, and some may be more updated than others.

...and we also have some documentation that could help:
