From e3c68bbba30b212326fb69bf64b2220750dead3e Mon Sep 17 00:00:00 2001
From: Jonas Gorski <jogo@openwrt.org>
Date: Sun, 30 Nov 2014 20:20:30 +0100
Subject: [PATCH 20/20] 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.
