Merge tag 'for-v3.10' of git://git.infradead.org/battery-2.6
Pull battery updates from Anton Vorontsov:
"Highlights:
- OpenFirmware/DeviceTree support for the Power Supply core: the core
now automatically populates supplied_from hierarchy from the device
tree. With these patches chargers and batteries can now lookup
each other without the board files support shim. Rhyland Klein at
NVIDIA did the work
- New ST-Ericsson ABX500 hwmon driver. The driver is heavily using
the AB85xx core and depends on some recent changes to it, so that
is why the driver comes through the battery tree. It has an
appropriate ack from the hwmon maintainer (i.e. Guenter Roeck).
Martin Persson at ST-Ericsson and Hongbo Zhang at Linaro authored
the driver
- Final bits to sync AB85xx ST-Ericsson changes into mainline. The
changes touch mfd parts, but these were acked by the appropriate
MFD maintainer (ie Samuel Ortiz). Lee Jones at Linaro did most of
the work and lead the submission process.
Minor changes, but still worth mentioning:
- Battery temperature reporting fix for Nokia N900 phones
- Versatile Express poweroff driver moved into drivers/power/reset/
- Tree-wide: use devm_kzalloc() where appropriate
- Tree-wide: dev_pm_ops cleanups/fixes"
