[PATCH] gpio: pxa: Set PXA GPIO irq_chip IRQCHIP_SKIP_SET_WAKE flag

[Robert Jarzmik]

Haojian,

I feel there's some change in PXA gpio wakeup handling that's weird.

The effect : gpio_keys driver can't wakeup from suspend to RAM on GPIO0
activation

A quick analysis (thanks Paul for direction) :
 - gpio_keys() calls irq_set_wake(96, 1) (ie. gpio0)
 - gpio-pxa driver doesn't care (as it doesn't have any irq_set_wake function)
   (see in [1])

Now if I'm directing the mail at is because you're the only one who commited
between v3.2 and v3.3 in gpio-pxa driver ([2]).

Could you tell me if removing irq_set_wake() was intentional ?

Cheers.
