+Required properties:
+ - compatible : "ti,twl4030-madc-battery"
+ - capacity-uah : battery capacity in uAh

Could we make it capacity-uAh ?

This name was suggested by Mark Rutland [1] and naming convention
should be all lowercase. There exists already bindings
without uppercase (e.g. ti,bb-uamp) so I would keep it consistent.

Would "mV-to-capacity..." be more accurate? Also, would it make sense

Again maybe mv but it can be added also later.

to introduce coefficients for temperature and discharge rate?

What do you mean? Nothing like that is used in current driver why do
we need to add it?

Temperature calibration should have already been done in the underlaying twl4030 iio driver.

Discharge rate is the real current flow reported in uA. Also reported by iio.
