Merge tag 'for-v3.12' of git://git.infradead.org/battery-2.6
Pull battery/power supply driver updates from Anton Vorontsov: "New drivers: - APM X-Gene system reboot driver by Feng Kan and Loc Ho (APM). - Qualcomm MSM reboot/poweroff driver by Abhimanyu Kapur (Codeaurora). - Texas Instruments BQ24190 charger driver by Mark A. Greer (Animal Creek Technologies). - Texas Instruments TWL4030 MADC battery driver by Lukas Märdian and Marek Belisko (Golden Delicious Computers). The driver is used on Freerunner GTA04 phones. Highlighted fixes and improvements: - Suspend/wakeup logic improvements: power supply objects will block system suspend until all power supply events are processed. Thanks to Zoran Markovic (Linaro), Arve Hjonnevag and Todd Poynor (Google)" * tag 'for-v3.12' of git://git.infradead.org/battery-2.6: rx51_battery: Fix channel number when reading adc value power: Add twl4030_madc battery driver. bq24190_charger: Workaround SS definition problem on i386 builds power_supply: Prevent suspend until power supply events are processed vexpress-poweroff: Should depend on the required infrastructure twl4030-charger: Fix compiler warning with regulator_enable() rx51_battery: Replace hardcoded channels values. bq24190_charger: Add support for TI BQ24190 Battery Charger ab8500-charger: We print an unintended error message max8925_power: Fix missing of_node_put power_supply: Replace strict_strtol() with kstrtol() power: Add APM X-Gene system reboot driver power_supply: tosa_battery: Get rid of irq_to_gpio usage power supply: collie_battery: Convert to use dev_pm_ops power_supply: Make goldfish_battery depend on GOLDFISH || COMPILE_TEST power: reset: Add msm restart support MAINTAINERS: drivers/power: add entry for SmartReflex AVS drivers
