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)
