[PATCH v3 35/47] arm: Register with kernel power-off handler

From: Guenter Roeck
Date: Mon Oct 27 2014 - 12:01:52 EST

Register with kernel power-off handler instead of setting pm_power_off
directly. Always use register_power_off_handler_simple as there is no
indication that more than one power-off handler is registered.

If the power-off handler only resets the system or puts the CPU in sleep mode,
select the fallback priority to indicate that the power-off handler is one
of last resort. If the power-off handler powers off the system, select the
default priority.

v3:
- Replace poweroff in all newly introduced variables and in text
with power_off or power-off as appropriate
- Replace POWEROFF_PRIORITY_xxx with POWER_OFF_PRIORITY_xxx
v2:
- Use defines to specify poweroff handler priorities
- Drop changes in arch/arm/mach-at91/setup.c (file removed upstream)
