Subject[PATCH v2 5/5] power: supply: core: supply battery soc with decimal form
Date
From: Qiwu Huang <huangqiwu@xiaomi.com>

Broadcast battery soc with decimal form.
soc_decimal is the decimal part of battery soc.
soc_decimal_rate is update frequency of decimal
part of battery soc.
We want to report such as 0.01 to 99.99% to
user space to improve user experience
when do very quick charging.
