200c0a3e40 Power: Reset: Generalize qnap-poweroff to work on Synology devices.
The Synology NAS devices use a very similar mechanism to QNAP NAS
devices to power off. Both send a single charactor command to a PIC,
over the second serial port. However the baud rate and the command
differ. Generalize the driver to support this.

d118966c58 power: reset: msm - switch Kconfig to ARCH_QCOM depends
We've split Qualcomm MSM support into legacy and multiplatform.  The reset
driver is only relevant on the multiplatform supported SoCs so switch the
Kconfig depends to ARCH_QCOM.

a2c0206ad6 vexpress-poweroff: Should depend on the required infrastructure
ARM Versatile Express reset driver requires platform-specific config
infrastructure to be present in the kernel. When VEXPRESS_CONFIG is not
selected, the build will fail like this:

drivers/built-in.o: In function `vexpress_reset_do.clone.0':
iio-trig-interrupt.c:(.text+0x1aff38): undefined reference to `__vexpress_config_func_get'
iio-trig-interrupt.c:(.text+0x1aff4c): undefined reference to `vexpress_config_write'

b52eafcd79 power/reset: Make the vexpress driver optional on arm and arm64
The driver can be used on either arm or arm64 platforms, but
the latter doesn't have any platform-specific configuration
options, so it must be possible to manually enable the driver.

5a1203914a 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"

Pull ARM SoC fixes from Olof Johansson:
 "People are back from the holiday breaks, and it shows.  Here are a
  bunch of fixes for a number of platforms:
   - A couple of small fixes for Nomadik
   - A larger set of changes for kirkwood/mvebu
     - uart driver selection, dt clocks, gpio-poweroff fixups, a few
       __init annotation fixes and some error handling improvement in
       their xor dma driver.
   - i.MX had a couple of minor fixes (and a critical one for flexcan2
     clock setup)
   - MXS has a small board fix and a framebuffer bugfix
   - A set of fixes for Samsung Exynos, fixing default bootargs and some
     Exynos5440 clock issues
   - A set of OMAP changes including PM fixes and a few sparse warning
     fixups

  All in all a bit more positive code delta than we'd ideally want to
  see here, mostly from the OMAP PM changes, but nothing overly crazy."

ffd8f9a727 power/reset: Add a new driver implementing 'power off by restarting'
Some devices, Buffalo Linkstation LS-XHL and LS-CHLv2 for example,
power-off by restarting to letting u-boot hold the SoC until the user
presses a key. Add a generic driver to implement this. It binds a function
to pm_power_off, which calls arm_pm_restart.

6d2cea4fca Drivers: power: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitconst,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.
