| |
On the Armada 370/XP/38x/39x SoCs when the suspend to ram feature is supported, the SoC is shutdown and will be waken up by an external micro-controller, so there is no possibility to setup wake-up source from Linux. However, in standby mode, the SoCs stay powered and it is possible to wake-up from any interrupt sources. As, when user decide to setup a wake-up source, there is no way to know if they will be wake-up source from suspend or from standby, then we chose allowing to setup all the interrupt as wake-up sources.
The purpose of this patch is to inform the user that in suspend to ram mode, the wake-up sources won't be taken into consideration.
