Subject: [PATCH 2/5] ARM: omap: update GPIO chained IRQ handler to use EOI in parent chip
Date: Tue, 22 Feb 2011 10:18:05 -0800 [thread overview]
Message-ID: <20110222181805.GM15225@atomide.com> (raw)
In-Reply-To: <1298302096-21275-3-git-send-email-will.deacon@arm.com>
* Will Deacon <will.deacon@arm.com> [110221 07:28]:
> 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.
