[PATCH 05/11] irqchip/bcm2835: Enable SKIP_SET_WAKE and MASK_ON_SUSPEND

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The BCM2835 ARMCTRL interrupt controller doesn't provide any facility
to configure the wakeup sources. That's the reason why this
implementation lacks the irq_set_wake implementation. But this prevent
us from properly entering power management states like "suspend to
idle".

So enable the flags IRQCHIP_SKIP_SET_WAKE and
IRQCHIP_MASK_ON_SUSPEND to let the irqchip core allows and handles
the power management.
