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)"
