[PATCH 31/44] arm: Register with kernel poweroff handler

Guenter Roeck
2014-10-07T05:28:33Z

Register with kernel poweroff handler instead of setting pm_power_off
directly. Always use register_poweroff_handler_simple as there is no
indication that more than one poweroff handler is registered.

If the poweroff handler only resets the system or puts the CPU in sleep mode,
select a priority of 0 to indicate that the poweroff handler is one of last
resort. If the poweroff handler powers off the system, select a priority
of 128.
