Does this need to be in the DT or could it be a runtime control (eg, for
a system that supports being rotated to adjust which speaker things go
out of).

This is usually a runtime control too.  This applies to a bunch of the
properties TBH.

At some point in the file we stop having a blank line between the
properties.

The driver has regulator support but there's no regulator properties
documented anywhere in the binding document.
