When the wakeup attribute is set, GPIO button is supposed to set
irqflag - IRQF_NO_SUSPEND to request irq. So when the system enters
the suspend sleep mode, the GPIO irq keeps enabled and is able to
wake the system up.
I think when we say irq_wake_enable() then based on underlying HW, it
should not turn off the irq if it is require for the wakeup. I mean it
need to be handle in the hw specific callbacks to keep enabling the
wakeup irq on suspend also.
For me, I have key which is interrupt based from PMIC, not based on GPIO
and on that if I set it to IRQF_EARLY_RESUME then it works fine.
