Series AB8500 charger to use power_supply_battery_info | expand

Commit Message

Linus Walleij Nov. 20, 2021, 3:53 p.m. UTC
Now that we know that we have only one battery type to
deal with we can proceed to transfer properties to
struct power_supply_battery_info.

The designed capacity for the battery was in a custom field
of the custom battery type in mAh, transfer this to the
standard charge_full_design_uah property in
struct power_supply_battery_info and augment the code
accordingly.
