Re: [PATCH v2] msm: gpio: Add set_wake support to msm7200a-gpio's irq_chip.

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

 



Add power-management and irq_chip hooks to allow configuration
of msm-gpio irq lines as wakeup sources.

What level of correlation is there between power management and the wake
up hooks? Just irq_masks ?

When the system sleeps, gpio-based irqs which are not configured as wake-up sources are disabled in the controller hardware to prevent latching and unwanted wakeups.
