power_supply: Convert drivers/power/* to use module_platform_driver()

2012-01-04T05:12:07+00:00

This patch converts the drivers in drivers/power/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

olpc_battery: Remove unneeded 'olpc_battery_trigger_uevent'

2011-11-24T19:07:00+00:00

It is no longer used, so we can safely remove it.

olpc_battery: Fix section mismatch noise

2011-11-24T18:51:52+00:00

This patch fixes the following noise (by renaming _drv to _driver):

WARNING: drivers/power/olpc_battery.o(.data+0x100): Section mismatch in reference from the variable olpc_battery_drv to the function .devinit.text:olpc_battery_probe()
The variable olpc_battery_drv references
the function __devinit olpc_battery_probe()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console

olpc_battery: Add wakeup support

2011-08-19T17:03:25+00:00

Battery and AC events can now be used to wake up the system from suspend.

olpc_battery: Bind to device tree

2011-08-19T17:03:24+00:00

This is cleaner, and allows suspend/resume (wakeup) handlers to be
added in an upcoming patch.

olpc_battery: Fix up XO-1.5 properties list

2011-01-12T22:41:57+00:00

The patches adding support for CURRENT_NOW, VOLTAGE_NOW, CHARGE_NOW and
CHARGE_FULL_DESIGN were based on a tree not including c566d299
("olpc_battery: Ambient temperature is not available on XO-1.5") and
therefore only modified the then-common, now-XO-1 properties list. This
patch adds the new properties to XO-1.5 as well.

olpc_battery: Add support for CURRENT_NOW and VOLTAGE_NOW

2011-01-12T17:29:20+00:00

{CURRENT,VOLTAGE}_AVG are actually {CURRENT,VOLTAGE}_NOW (the EC code
directly passes through the value from the gas gauge instead of the
internally used average). We retain {CURRENT,VOLTAGE}_AVG as an alias
for compatibility reasons, it will be removed later.

olpc_battery: Add support for CHARGE_NOW

2011-01-12T17:29:00+00:00

CHARGE_NOW is needed by some user space software (read: UPower) for
internal calculations.

This patch violates the power supply class definition (as we already
do for CAPACITY though it isn't as obvious there), but this is the best
we can do without adding rather sophisticated algorithms to either the EC
or UPower.

olpc_battery: Add support for CHARGE_FULL_DESIGN

2011-01-12T17:28:45+00:00

Some user space software (read: UPower) uses CHARGE_FULL_DESIGN for internal
calculations. The design capacity of the OLPC batteries is effectively fixed
and only needs to be exported.

olpc_battery: Ambient temperature is not available on XO-1.5

2011-01-12T17:28:24+00:00

The XO-1.5 does not support the ambient temperature property.
Create a separate list of properties for that configuration where
ambient temperature is not included, and apply the correct property
list at runtime.
