"MSS" doesn't appear below, so perhaps an expansion in parentheses would
be nice, e.g.: "MSS (microprocessor subsystem)"

The file name and compatible string are inconsistent in phrasing
(mpfs- vs. polarfire-soc-). If possible, please align them.

Quotation marks are unnecessary here, because there are no special
characters in "mboxes".

'description'?

Perhaps including some info about what this block does and how it is 
accessed.

All this is defined already in the common binding schema, drop.

Don't need quotes.
