The subject is still pretty generic. Ideally, we'd never have the same subject twice. I'd do something like this:
ASoC: dt-bindings: awinic,aw88395: Add properties for multiple PA support
Adds properties to "awinic,aw88395" to make files more complete
Complete in what way? multiple PAs, right. It's not really clear to me though how these properties enable support for multiple PAs.
