Dan / Sebastian, I wasn't able to find the subsequent patches
that add the 3 health properties, so I'm assuming this patch is still
"out-of-tree".

I was hoping against that so we (Android) aren't unnecessarily diverging
from upstream. However, I have now just cherry-picked this patch[1] for the
next Android release.

Sebastian, since these appear in JEITA spec, will the same patch with
additions to the commit message saying so be enough?

Thanks,
