To avoid cc-ing people to DTs they are not related, the get_maintainers.pl
script was run on each patch individually. The cover-letter is at:

I think Neil's question is the same as mine: is there a dt-bindings
(yaml schema) change for this as well? The idea is to alert people (or
let bots alert people) in future when adding a cache to a .dts{,i}
where the cache-level property is missing.

There's not one, but it's something to look at adding. I'm not sure
how we'd check for missing 'unified-cache' which is a common problem.
The challenge here is a lot of what needs to be checked is based on
the overall structure. This probably is better checked in dtc which is
better suited to do cross node checks.

Now there is an improved binding:

https://github.com/robherring/dt-schema/tree/cache-rework

Thanks for the branch, I used it to make the v2. I don't think it is likely
to happen, but dt-schema doesn't generate a warning if there is a
'unified-cache' property along a '[d|i]-cache-size' property (for instance).

With that schema and this series applied, I get the following errors:
