[PATCH v2 06/16] power: supply: ab8500: Standardize design capacity
From: Linus Walleij <hidden>
Date: 2021-11-20 15:55:54

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.
