power: supply: act8945a_charger: Add capacity level property

2016-09-01T11:55:52+00:00

Add the power supply capacity level property, it corresponds to
POWER_SUPPLY_CAPACITY_LEVEL_*.

It also utilizes the precision voltage detector function module
to catch the low battery voltage.

power: supply: act8945a_charger: Fix the power supply type

2016-08-31T14:47:01+00:00

The power supply type property is varying as the external power
supply changes. It is not a constant.

power: supply: act8945a_charger: Add status change update support

2016-08-31T14:46:57+00:00

Add the charger status change interrupt support, it will report
the power supply changed event.

This interrupt is generated by one of the conditions as below:
 - the state machine jumps out of or into the EOC state
 - the CHGIN input voltage goes out of or into the valid range.
 - the battery temperature goes out of or into the valid range.
 - the PRECHARGE time-out occurs.
 - the total charge time-out occurs.

power: supply: act8945a_charger: Improve state handling

2016-08-31T14:46:54+00:00

When get the property, first check the charger state machine,
then check the status bit to decide what value is assigned to
the corresponding property.

Retain the SUSCHG bit of REG 0x71 when configure the timers to
avoid losting the charger suspending info after boot.

power: supply: act8945a_charger: Remove "battery_temperature"

2016-08-31T14:46:50+00:00

Remove "battery_temperature" member, it is redundant, it is the
hardware's responsibility to handle TH pin properly.
It is unnecessary to use the dt property to check if there is
a battery temperature monitor or not.

power: supply: act8945a_charger: Achieve properties from its node

2016-08-31T14:46:43+00:00

Since the act8945a_charger is regarded as a sub-device, all properties will
be assigned to its own device node. All properties can be achieved from its
own node, instead of from its parent device.

power: move power supply drivers to power/supply

2016-08-10T23:11:03+00:00

This moves all power supply drivers from drivers/power/
to drivers/power/supply/. The intention is a cleaner
source tree, since drivers/power/ also contains frameworks
unrelated to power supply, like adaptive voltage scaling.
