gpio interrupt support

gpio interrupt support

[Brian Swetland]

I need to handle interrupts from omap gpios... it looks like there's
code for (most of?) this in plat-omap/gpio.c, but the interrupt related
functions are static and not exported.  Is this functionality incomplete
or is there some other way to register gpio interrupt handlers that I'm
overlooking?

Thanks,

Brian

Sounds like OMAP_GPIO_IRQ() is probably what you are after. Look at
plat-omap/gpio-switch.c as an example.

gpio.c extends the system IRQs by the number of OMAP GPIO pins. You use
request_irq() to subscribe a GPIO IRQ. See Ethernet driver for details.
