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 ...

2013-02-16generic-adc-battery: Fix forever loop in gab_remove()Dan Carpenter
There is a forever loop calling iio_channel_release() because the "chan < " part of the "chan < ARRAY_SIZE()" is missing. This is in both the error handling on probe and also in the remove function. The other thing is that it's possible for some of the elements of the adc_bat->channel[chan] array to be an ERR_PTR(). I've changed them to be NULL instead. We're still not allowed to pass NULLs to iio_channel_release() so I've added a check. Finally, I removed an unused "chan = ARRAY_SIZE(gab_chan_name);" statement as a small cleanup.

2013-01-23u8500-charger: Delay for USB enumerationPaer-Olof Haakansson
If charging is started before USB enumeration of an Accessory Charger Adapter has finished, the AB8500 will generate a VBUS_ERROR. This in turn results in timeouts and delays the enumeration with around 15 seconds. This patch delays the charging and then ramps currents slowly to avoid VBUS errors. The delay allows the enumeration to have finished before charging is turned on.
