> On OMAP4, gpio_irq_handler can be chained to a physical interrupt using
> the GIC as the primary IRQ chip. Now that the GIC uses the fasteoi flow
> model, the chained handler must invoke ->irq_eoi once handling is
> complete.
> 
> This patch adds a conditional call to ->irq_eoi in the GPIO IRQ handler
> for OMAP platforms. For OMAP implementations using other primary
> interrupt controllers, the ->irq_ack call remains and is also made
> conditional on the support offered by the controller.
