Subject: [PATCH 4/6] arm: dts: Change PCIe INTx mapping for NSP
Date:   Tue, 29 May 2018 14:58:48 -0700
Message-Id: <1527631130-20045-5-git-send-email-ray.jui@broadcom.com>

Precedence: bulk

Change the PCIe INTx mapping to model the 4 INTx interrupts in the
IRQ domain of the iProc PCIe controller itself
