The power supply name used to be fixed as "battery". This change allows
for multiple batteries by generating the name rather than using a fixed

This driver for the bq20z75 implemented the register spec defined
by the SBS standard. As this is not unique to this the TI part this
was originally written for, we can generalize this driver to
show its support for any SBS compliant battery.Signed-off-by: Rhyland Klein

DEFINE_MUTEX() rather than explicitly calling mutex_init().This patch also removes an unused bat_lock mutex.

1. Useless braces were omitted
2. Useless void casts were omitted
3. module exit name changed

Charger Manager provides power-supply-class aggregating
information from multiple chargers and a fuel-gauge.Signed-off-by: Donggeun Kim

Signed-off-by: Kyungmin Park
Signed-off-by: Anton Vorontsov -
Because battery health monitoring should be done even when suspended,
it needs to wake up and suspend periodically. Thus, userspace battery
monitoring may incur too much overhead; every device and task is woken
up periodically. Charger Manager uses suspend-again to provide
in-suspend monitoring.This patch allows to monitor battery health in-suspend state.

Make the relationship between the Wiimote and Wacom self-powered HID
devices and their power supply explicit by adding a "powers" link.Signed-off-by: Jeremy Fitzhardinge
Cc: Jiri Kosina -
The Wacom and Wiimote HID drivers register power supplies for themselves
to indicate their battery levels. Make those power supplies device scope.Signed-off-by: Jeremy Fitzhardinge
Cc: Jiri Kosina -
If a power supply has a scope of "Device", then allow the power supply
to indicate what device it actually powers. This is represented in the
power supply's sysfs directory as a symlink named "powers", which points to
the sysfs directory of the powered device.If the device has children, then the sub-devices are also powered by
the same power supply.Signed-off-by: Jeremy Fitzhardinge
Cc: Richard Hughes -
This adds a "scope" attribute to a power_supply, which indicates how
much of the system it powers. It appears in sysfs as "scope" or in
the uevent file as POWER_SUPPLY_SCOPE=. There are presently three
possible values:
Unknown - unknown power topology
System - the power supply powers the whole system
Device - it powers a specific device, or tree of devicesA power supply which doesn't have a "scope" attribute should be assumed to
have "System" scope.In general, usermode should assume that loss of all System-scoped power
supplies will power off the whole system, but any single one is sufficient
to power the system.Signed-off-by: Jeremy Fitzhardinge

Since commit [e58aa3d2: genirq: Run irq handlers with interrupts
disabled], We run all interrupt handlers with interrupts disabled
and we even check and yell when an interrupt handler returns with
interrupts enabled (see commit [b738a50a: genirq: Warn when handler
enables interrupts]).So now this flag is a NOOP and can be removed.

events to be passed to drivers what are listed in the
supplied_to call back field. Enable this feature by
allowing the supplied_to field to be passed to the driver.This feature will enable drivers named in the supplied_to
