power_supply: Add watchdog and safety timer expiries under PROP_HEALTH_*

2013-01-06T02:51:18+00:00

As most of the charger chips come with two kinds of safety features
related to timing:

1. Watchdog Timer (interms of seconds/mins)
2. Safety Timer (interms of hours)

This patch adds these to fault causes in POWER_SUPPLY_PROP_HEALTH_* enums
so that whenever there is either watchdog timeout or safety timer timeout
driver could notify the user space accurately about the fault and will
also be helpful for debug.

power_supply: Add support for CHARGE_CONTROL_* attributes

2012-11-18T04:21:43+00:00

Add support for power supply attributes CHARGE_CONTROL_LIMIT
and CHARGE_CONTROL_LIMIT_MAX.

These new attributes will enable the user space to implement
custom charging algorithms based on platform state.

power_supply: Add new power supply properties CHARGE_CURRENT/VOLTAGE_MAX

2012-08-23T04:59:15+00:00

There are different types of chargers avalibale like AC, Solar, USB,
etc..  Even in USB we have different types SDP/DCP/CDP/ACA and all these
chargers have different o/p ratings. For example SDP supports only 500mA
of charge current whereas AC charger can support upto 8A or more.

Similarly batteries also come with charge current and voltage ratings
and these ratings vary depending on its capacity and the technology
used.

This patch adds two new power supply properties
CONSTANT_CHARGE_CURRENT_MAX and CONSTANT_CHARGE_CURRENT_MAX.

power_supply: Add new power supply AUTHENTIC property

2012-08-23T02:56:37+00:00

It is possible that users can use non-standard chargers or use invalid
batteries especially with mobile devices.

This patch adds a new power supply property called 'AUTHENTIC' to
indicate this to the user(user space).

power_supply: Add min/max alert properties for CAPACITY, TEMP, TEMP_AMBIENT

2012-07-14T03:41:58+00:00

Minimum and maximum alerts on power supply properties will help or allow
the user space to "proactively" create policies like connect/disconnect
charger or stop/start the user apps based on capacity or temperature
parameters.

These parameters can be used to avoid unnecessary polling from user space
and even from kernel space if the underlying HW can support INT triggers
(ex: max17042/47).

This patch adds the following power supply alert type properties:

 CAPACITY_ALERT_MIN
 CAPACITY_ALERT_MAX
 TEMP_ALERT_MIN
 TEMP_ALERT_MAX
 TEMP_AMBIENT_ALERT_MIN
 TEMP_AMBIENT_ALERT_MAX

power_supply: Add constant charge_current and charge_voltage properties

2012-06-19T23:46:58+00:00

Constant Charge Current(CC) is charging parameter which limit the
maximum current which can be pumped into the battery during charge cycle.

Constant Charge Voltage(CV) is also charging parameter which limit the
maximum voltage that battery can reach during charge cycle.

It is very common practice that at low or high temperatures we
do not charge the batteries upto it's fullest charge voltage
to avoid battery and user safety issues.

These sysfs properties will be useful for debug and to implement
certain user space policies like "Charging limited due to OverTemp".

power_supply: Add voltage_ocv property and use it for max17042 driver

2012-05-05T03:44:29+00:00

This adds a new sysfs file called 'voltage_ocv' which gives the
Open Circuit Voltage of the battery.

This property can be used for platform shutdown policies and
can be useful for initial capacity estimations.

device.h: cleanup users outside of linux/include (C files)

2012-03-11T18:27:37+00:00

For files that are actively using linux/device.h, make sure
that they call it out.  This will allow us to clean up some
of the implicit uses of linux/device.h within include/*
without introducing build regressions.

Yes, this was created by "cheating" -- i.e. the headers were
cleaned up, and then the fallout was found and fixed, and then
the two commits were reordered.  This ensures we don't introduce
build regressions into the git history.
