power_supply: get_by_name and set_charged functionality

2009-07-30T13:49:15+00:00

This adds a function that indicates that a battery is fully charged.
It also includes functions to get a power_supply device from the class
of registered devices by name reference. These can be used to find a
specific battery to call power_supply_set_battery_charged() on.

Some battery drivers might need this information to calibrate
themselves.

power_supply: Add a charge_type property, and use it for olpc driver

2009-07-02T14:14:37+00:00

This adds a new sysfs file called 'charge_type' which displays the
type of charging (unknown, n/a, trickle charge, or fast charging).

This allows things like battery diagnostics to determine what the
battery/EC is doing without resorting to changing the 'status' sysfs
output.

Revert "power: remove POWER_SUPPLY_PROP_CAPACITY_LEVEL"

2009-06-30T22:44:03+00:00

This reverts commit 8efe444038a205e79b38b7ad03878824901849a8 and
4cbc76eadf56399cd11fb736b33c53aec9caab8c.

Richard@laptop.org was apparently using CAPACITY_LEVEL for debugging
battery/EC problems, and was upset that it was removed.  This readds it.

ACPI: battery: add power_{now,avg} properties to power_class

2009-03-28T02:23:52+00:00

ACPI has smart batteries, which work in units of energy and measure
rate of (dis)charge as power, thus it is not appropriate to export it
as a current_now. Current_now will still be exported to allow
for userland applications to match.

power_supply: Add cold to the POWER_SUPPLY_HEALTH report values

2009-01-04T11:17:39+00:00

Some systems are able to report problems with batteries being under
temperature.

power_supply: Add function to return system-wide power state

2008-08-31T22:42:54+00:00

Certain drivers benefit from knowing whether the system is on ac or
battery, for instance when determining which backlight registers to
read. This adds a simple call to determine whether there's an online
power supply other than any batteries.

power_supply: add CHARGE_COUNTER property and olpc_battery support for it

2008-05-13T08:27:11+00:00

This adds PROP_CHARGE_COUNTER to the power supply class (documenting it
as well).  The OLPC battery driver uses this for spitting out its ACR
values (in uAh).  We have some rounding errors (the data sheet claims
416.7, the math actually works out to 416.666667, so we're forced to
choose between overflows or precision loss.  I chose precision loss,
and stuck w/ data sheet values), but I don't think anyone will care
that much.

ACPI: battery: add sysfs serial number

egrep serial /proc/acpi/battery/BAT0/info
serial number:           32090

serial number can tell you from the imminent danger
of beeing set on fire.

battery technology and voltage_min/_max properties support.
