This is one of the options. Other option is to extend the pmic/power
command to:

pmic charger on/off to recharge battery when needed.

I think, that above is a better solution.

Yes, indeed this shall be regarded as a proof-of-concept to show that
battery is automatically charged when needed.

Instead, I think, that it would be a good idea to write a warning on
the u-boot starting (when PMIC driver is initialized):

e.g. WARNING: Battery needs charging (voltage: 3.5V capacity: 8%)

And then user can on its own decide if he/she will charge the battery or
