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 arch/arm/mach-at91/pm.c | 93 ++++++++++++++++++++++++++++++++++++++--- arch/arm/mach-at91/pm.h | 5 ++- arch/arm/mach-at91/pm_suspend.S | 41 ++++++++++++++++-- 3 files changed, 127 insertions(+), 12 deletions(-) -- 2.7.4
