- 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.
- Signed-off-by: Jonas Gorski <jogo@openwrt.org>
