- 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
   (i.e. 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-wise: use devm_kzalloc() where appropriate;
 - Tree-wise: dev_pm_ops cleanups/fixes.
