I suppose there is a reason the sc7180 is being split out and the only
one converted, but this doesn't tell me.

Use 'items' to describe each entry.

You need to define this as a schema:

items:
- items:
- description: ...
- description: ...
- description: ...

I believe there's a common schema for this now or one pending so you
should drop the type here.

That's not sufficient for a phandle-array which is really a matrix.

Only 1, you can drop 'items'. And 'label' is always 1 entry.

I am also confused, especially that last time I pointed out that there
is work already:

The reason for the split was discussed on the list ^^, thought it
wouldn't make much sense adding any of it to the commit message.

Last time I checked all the other remoteprocs handle
them this way and there wasn't a common schema for it.

https://lore.kernel.org/all/[email protected]/#t

The reason for the split was discussed on the list ^^, thought it
wouldn't make much sense adding any of it to the commit message.
Also since Krzysztof said he wanted a alignment between Sireesh/me
we did exchange mails saying I'll take care of SC7180/SC7280 (since
they had pas compatible which is overridden by mss compatible) and
he could continue with the rest.

Sounds good to me, but Rob's got a point - this background should be
better explained.

Why not? If you did, then we wouldn't be having this conversation.

Commit messages, at a minimum, should answer why are you making the
change. They don't really need to explain what the change is. We can all
read the diff to understand that.
