Subject: [PATCH 08/12] MIPS: GIC: Implement generic irq_ack/irq_eoi callbacks
Date: Fri, 29 Aug 2014 15:14:35 -0700 [thread overview]
Message-ID: <1409350479-19108-9-git-send-email-abrestic@chromium.org> (raw)
In-Reply-To: <1409350479-19108-1-git-send-email-abrestic@chromium.org>
Implement a default gic_irq_ack() and gic_finish_irq(). These are
suitable for handling IPIs on Malta and the upcoming Danube board.
Signed-off-by: Andrew Bresticker <abrestic@chromium.org>
