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.

x86: sysfs: kill owner field from attribute

2008-10-20T15:52:42+00:00

Tejun's commit 7b595756ec1f49e0049a9e01a1298d53a7faaa15 made sysfs
attribute->owner unnecessary.  But the field was left in the structure to
ease the merge.  It's been over a year since that change and it is now
time to start killing attribute->owner along with its users - one arch at
a time!

This patch is attempt #1 to get rid of attribute->owner only for
CONFIG_X86_64 or CONFIG_X86_32 .  We will deal with other arches later on
as and when possible - avr32 will be the next since that is something I
can test.  Compile (make allyesconfig / make allmodconfig / custom config)
and boot tested.

akpm: the idea is that we put the declaration of sttribute.owner inside
`#ifndef CONFIG_X86'.  But that proved to be too ambitious for now because
new usages kept on turning up in subsystem trees.

[akpm: remove the ifdef for now]

power_supply: Fix race in power_supply_uevent

2008-06-09T22:13:51+00:00

Commit 54d29ad33e3483bcc7ca433a21cf294854e5154a (Power Supply: fix race
in device_create) introduced a race in power_supply_uevent. Previously it
checked that power_supply is available by checking for dev->driver_data.
But now dev->driver_data is set before power_supply->dev is initialised.

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.

power_supply: remove capacity_level from list of sysfs attributes

2008-02-07T16:42:06+00:00

This commit:

commit 8efe444038a205e79b38b7ad03878824901849a8

    power: remove POWER_SUPPLY_PROP_CAPACITY_LEVEL

Removed CAPACITY_LEVEL from every other code, leaving the array with sysfs
attributes with one more entry than the number of enums in power_supply.h.
This leads to some attributes containing the value of the attribute right
after it.  For example, temp_ambient would have the value of
time_to_empty_now.  In my case, I had time_to_full_avg have the value which
should be in model_name, when the former was usually empty.
