I just meant that I split this patch out of the patch that followed
(because of review feeback and
Documentation/devicetree/bindings/submitting-patches.txt rules).

Will do.

The tree seems inconsistent on formatting of these files, but I like
your suggestion for nicer formatting so I'll do it.

Oh, so have those two just smashed into this file as one set of
documentation for everything to do with mailbox on bcm2835? That seems
good to me. When I was adding the client drivers, the fact that the
other brcm file was named after the compatible string made me generate
new files under then new compatible strings, but the other drivers
already in the tree obviously aren't formatted that way.
