From 8720b255f5280fdf89decfa9ff31720aff1c4e49 Mon Sep 17 00:00:00 2001 From: Yuanjiang Yu Date: Mon, 20 Apr 2020 11:42:05 +0800 Subject: [PATCH] power: supply: sc27xx: Allow to change the battery full capacity The battery full capacity can be affected by the temperature or the servicing time or other factors, so some platforms will track the real battery full capacity in charger manager service. Thus we should allow to change the battery full capacity by setting the 'POWER_SUPPLY_PROP_ENERGY_FULL_DESIGN' property as writeable.
