[PATCH v2 0/3] AT91 PM improvements

[Claudiu Beznea]

Hi,

This series adds ULP0 fast mode intended to reduce the suspend/resume
time in the detriment of power consumption (patch 1/3).
Along with this patch 2/3 adds code to avoid requesting a PM mode
not available on platforms not supporting it.
Patch 3/3 decrements a device_node refcount after its usage.

Thank you,
Claudiu Beznea

Changes in v2:
- in patch 2/3:
	- move per SoC supported mode arrays in *_pm_init() functions.
	- use 2 booleans in at91_pm_modes_validate() for modes validation
	- continue to use array of supported modes in at91rm9200_pm_init()
	  and at91sam9_pm_init() instead of forcing
	  soc_pm.data.standby_mode = AT91_PM_STANDBY and
	  soc_pm.data.suspend_mode = AT91_PM_ULP0 to breaking the user
	  configuration (it might request ulp0 as standby mode or vice versa)
	  
Claudiu Beznea (3):
  ARM: at91: pm: add support for ULP0 fast wakeup
  ARM: at91: pm: add per soc validation of pm modes
  ARM: at91: pm: of_node_put() after its usage
