Nits:

The indentation is a little odd here; I'd expect the - to be in column
1, at least that's how most other binding docs are written. Not a big
deal though.

It'd be nice to indent the continuation lines (e.g. "mapped region") a
bit more so it's easier to see where each new entry starts.

There are two spaces in "mapped region".

Should those property names be prefixed with "st,"; I assume they're
specific to this binding rather than something generic that applies to
all IR controller bindings? If you expect them to be generic, it's fine.

For what clock?
