From: Haibo Chen haibo.chen@nxp.com
commit 430232619791e7de95191f2cd8ebaa4c380d17d0 upstream.
Add flag IRQCHIP_MASK_ON_SUSPEND to make sure gpio irq is masked on suspend, if lack this flag, current irq arctitecture will not mask the irq, and these unmasked gpio irq will wrongly wakeup the system even they are not config as wakeup source.
Also add flag IRQCHIP_ENABLE_WAKEUP_ON_SUSPEND to make sure the gpio irq which is configed as wakeup source can work as expect.
