No need for the ().

These can be moved to the previous pattern prop and removed from each
entry.

And this. And then just do 'st,mask-reset: true'.

Fixed string, not a pattern.

Not sure this is worth its own entry just to exclude
'regulator-enable-ramp-delay'.

Not documented. And didn't warn because an 'additionalProperties: false'
