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
