While changing it, make the node names generic, so:

speaker@0,3

Hi,

This is a bit surprising. You pointed to Linus' repo, so what does this
dependency mean? The Linus' repo is the mainline, there is nothing else,
so all its commits are already in every tree... unless this is an RC
fix? If so, you should rather say which RC is needed.

That's interesting, let's check:
$ git grep -C 4 patternProperties -- Documentation/devicetree/bindings/

First has description, second does not have, third has, 4th has, 5th
has, 6th has, 7th has, 8th has.

So from all first 8 entries, only one did not have. When the objects are
obvious or are a standard properties, the description could be skipped,
but in regular cases description is expected. Just like for every custom
property.

> You mean, description for below compatible property?

No, description on the level of type: object.

You have two interrupts but only one name.
