Thanks Rob. I'm unsure what I have been thinking of :( I'll fix this
for next version.

I know but these are existing properties. I'd like to re-use them as
they have exported parser helpers - and I am unsure what kind of
breakages changing them would cause. (The BD71837/BD71847 which
introduced these properties are one of the PMICs which are pretty
widely used.)
