I think you mean constant-charge-* which is how you surface these
properties in your tps65217_charger patch.

I'll add these to v14 of my patchset which adds simple-battery
support. Rob requested a single patch for this file.

I've been waiting for feedback on v13.2 from Sebastian. If I don't
hear from him within a few days, I'll post v14.
