From 4fd286c3e5a5bebab0391cf1937695b3ed6721a3 Mon Sep 17 00:00:00 2001
From: Jonas Gorski <jogo@openwrt.org>
Date: Sun, 30 Nov 2014 20:20:30 +0100
Subject: [PATCH 4/5] MIPS: BCM63XX: wire up BCM6358's external interrupts 4
and 5
Due to the external interrupts being non consecutive, the previous
implementation did not support them. Now that we treat both registers
as separate irq controllers, there is no such limitation anymore and
we can expose them for drivers to use.
