Series pm8916: Add BMS and charger |

  pm8916 contains some hardware blocks for battery powered devices:

- VM-BMS: Battery voltage monitoring block.
- LBC: Linear battery charger.

Add them to the pmic dtsi so the devices that make use of those blocks
can enable them.

"battery" is not a valid child of the pmic according to
mfd/qcom,spmi-pmic.yaml, so please update the binding to remove the
warnings that this introduces.

Thanks,

This should be done in 1/3 which is already accepted to mfd,
so the warning should be gone when the stuff is pulled together.

Sorry for not making sure it's in earlier

Very good. I just didn't spot that for some reason.

No fault on your part, I should have spotted it. Sending binding updates
and DT updates in the same series is preferred way, and as I don't apply
the binding through my tree these warnings show up there.

Thank you,
