Subject: [PATCH 2/2] ARM: dts: imx: fix invalid #address-cells value
Date: Thu, 13 Mar 2014 10:40:05 -0700
Message-Id: <1394732405-2260-3-git-send-email-tharvey@gateworks.com>
In-Reply-To: <1394732405-2260-1-git-send-email-tharvey@gateworks.com>
References: <1394732405-2260-1-git-send-email-tharvey@gateworks.com>
Sender: linux-pci-owner@vger.kernel.org
List-ID: <linux-pci.vger.kernel.org>

The invalid value of #address-cells in the imx6 pcie host controller node
causes of_irq_parse_raw() to incorrectly advance through an interrupt-map
table of more than one interrupt.

This patch resolves this issue and allows proper interrupt mapping for an
imx6 pcie host connected to a P2P bridge when using legacy interrupts.
