It's a bit late for v6.18 content, since the merge window likely opens
on Monday, but how do you intend getting the series into mainline?

There is a document https://docs.kernel.org/process/maintainer-soc.html
containing information about how the platform maintenance process works.
Arnd has suggested that the best way to get a platform initially added
is to send the whole patchset, rather than a PR - it leaves you with
fewer things to deal with at once. This patchset should be sent to
soc@...nel.org, with a note saying that it is ready for inclusion in
your cover letter. 

Ideally, the initial patchset for an SoC should contain clock (and
pinctrl) support, rather than use fake fixed-clocks, but you have none of
those in your base dts so I have no objections. fixed-clocks can become
a problem if the dts is imported into U-Boot via OF_UPSTREAM or
elsewhere, since it can cause regressions for them. I would highly
suggest that upstreaming the clock/reset controller is the next step
that you take, because other peripherals are going to need clocks.

Please let me know if you have any questions - either by email (and it
can be off-list if needed if it relates to platform maintenance
questions) or on irc (I'm conchuod on libera.chat).

Cheers,
Conor.
