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" * tag 'for-v3.10' of git://git.infradead.org/battery-2.6: (112 commits) pm2301-charger: Fix suspend/resume charger-manager: Use kmemdup instead of kzalloc + memcpy power_supply: Populate supplied_from hierarchy from the device tree power_supply: Add core support for supplied_from power_supply: Define Binding for power-supplies rx51_battery: Fix reporting temperature hwmon: Add ST-Ericsson ABX500 hwmon driver ab8500_bmdata: Export abx500_res_to_temp tables for hwmon ab8500_{bmdata,fg}: Add const attributes to some data arrays ab8500_bmdata: Eliminate CamelCase warning of some variables ab8500_btemp: Make ab8500_btemp_get* interfaces public goldfish_battery: Use resource_size() lp8788-charger: Use PAGE_SIZE for the sysfs read operation max8925_power: Use devm_kzalloc() da9030_battery: Use devm_kzalloc() da9052-battery: Use devm_kzalloc() ds2760_battery: Use devm_kzalloc() ds2780_battery: Use devm_kzalloc() gpio-charger: Use devm_kzalloc() isp1704_charger: Use devm_kzalloc() ...
2013-04-16pm2301-charger: Fix suspend/resumeLars-Peter Clausen
The pm2301-charger driver implements runtime pm and at the same time uses the legacy pm callbacks for suspend and resume. This does not work since the I2C core wont look at the legacy pm callbacks if a driver has the 'pm' field set. This patch fixes it by moving over to dev_pm_ops for suspend/resume as well.
