Subject: [PATCH 24/24] MIPS: sead3: Use generic plat_irq_dispatch
Date: Mon, 15 Sep 2014 16:51:27 -0700 [thread overview]
Message-ID: <1410825087-5497-25-git-send-email-abrestic@chromium.org> (raw)
In-Reply-To: <1410825087-5497-1-git-send-email-abrestic@chromium.org>
The generic plat_irq_dispatch provided in irq_cpu.c is sufficient for
dispatching interrupts on SEAD-3 in legacy and vectored interrupt modes.
