Merge tag 'for-v3.9' of git://git.infradead.org/battery-2.6
Pull battery updates from Anton Vorontsov: "Four new drivers: - goldfish_battery: This is Android Emulator battery driver. Originally from Google, but Intel folks reshaped it for mainline - pm2301_charger: A new driver for ST-Ericsson 2301 Power Management chip, uses AB8500 battery management core - qnap-poweroff: The driver adds poweroff functionality for QNAP NAS boxes - restart-poweroff: A generic driver that implements 'power off by restarting'. The actual poweroff functionality is implemented through a bootloader, so Linux' task is just to restart the box. The driver is useful on Buffalo Linkstation LS-XHL and LS-CHLv2 boards. Andrew Lunn worked on submitting the driver (as well as qnap-poweroff above). Additionally: - A lot of fixes for ab8500 drivers. This is a part of efforts of syncing internal ST-Ericsson development tree with the mainline. Lee Jones @ Linaro worked on compilation and reshaping these series. - New health properties for the power supplies: "Watchdog timer expire" and "Safety timer expire" - As usual, a bunch of fixes/cleanups here and there" * tag 'for-v3.9' of git://git.infradead.org/battery-2.6: (81 commits) bq2415x_charger: Add support for offline and 100mA mode generic-adc-battery: Fix forever loop in gab_remove() goldfish_battery: Add missing GENERIC_HARDIRQS dependency da9030_battery: Include notifier.h bq27x00_battery: Fix reporting battery temperature power/reset: Remove newly introduced __dev* annotations lp8727_charger: Small cleanup in naming ab8500_btemp: Demote initcall sequence ds2782_battery: Add power_supply_changed() calls for proper uevent support power: Add battery driver for goldfish emulator u8500-charger: Delay for USB enumeration ab8500-bm: Remove individual [charger|btemp|fg|chargalg] pdata structures ab8500-charger: Do not touch VBUSOVV bits ab8500-fg: Use correct battery charge full design pm2301: LPN mode control support pm2301: Enable vbat low monitoring ab8500-bm: Flush all work queues before suspending ab8500-fg: Go to INIT_RECOVERY when charger removed ab8500-charger: Add support for autopower on AB8505 and AB9540 abx500-chargalg: Add new sysfs interface to get current charge status ... Fix up fairly straightforward conflicts in the ab8500 driver. But since it seems to be ARM-specific, I can't even compile-test the result..
