Hi Jason,

Thanks a lot for your submission!

I'm glad to see Cortina Access is getting back to upstreaming
this support, I see that you first tries this in 2021 but
didn't get very far at the time. The last submission was v4,
so it would make sense to cound this one as v5 and continue
with v6 next time.

You have already received a number of comments, so I'll skip
looking at the details for the moment and let you work through
them.

Regarding how to split up the patch series between uart and
soc, I think sending them together during the review phase
as you do here makes sense, but as they are loosely coupled,
I think we will likely merge them separately. For simplicity,
I would then just put the MAINTAINERS entry and the bindings
for the vendor and board into the series for the soc tree.

It would also help me if you could add some more context about
the SoC into the patch description for the patch that adds
the arm64 platform, in particular:

 - is this the only one you are planning to upstream at this
   point, or do you already have plans for other SoCs in this
   family?

 - do you expect to see full support for actual end-user
   products using these chips?

 - is there any shared lineage with the cortina-systems
   (storlink/storm, now marvell) gemini 32-bit chips that we
   already support, or with any of the Realtek SoCs that
   are also being upstreamed now?
