Heiko Stuebner 76ee875c2f power: reset: gpio-poweroff: add ability to specific active and inactive delays
Similar to gpio-reset allow to specify active and inactive delays
while keeping the 100ms defaults that were used previously all the time.

The dt-properties are named the same as in gpio-reset but get an "-ms"
suffix as properties should contain such a suffix specifying its unit.

Mike Looijmans 77142a6112 gpio-poweroff: Use gpiod_set_value_cansleep
The power-off call is done in a context that must be able to sleep, so
use gpiod_set_value_cansleep instead of the atomic gpiod_set_value call.

This fixes a kernel warning at shutdown when the gpio is controlled
through an IO expander for example.

Since 39b2bbe3d7 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for output.

Linus Walleij 86336ba4b7 power: poweroff: gpio: convert to use descriptors
This switches the GPIO poweroff driver to use GPIO descriptors
rather than numeral GPIOs. We get rid of the specific inversion
handling as GPIO descriptors know if they are active low or
high and can assert the line properly, so we do not need to
check the flag OF_GPIO_ACTIVE_LOW returned from the old call
of_get_gpio_flags() anymore.

Also convert to use managed resources and use dev_* message
printing while we're at it.

Linus Torvalds 974b33586b ARM: arm-soc fixes for 3.8-rc
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.

Greg Kroah-Hartman 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.
