Subject: [PATCH v3 4/6] arm: dts: Change PCIe INTx mapping for NSP
Date:   Tue,  3 Dec 2019 10:27:04 +0530
Message-Id: <1575349026-8743-5-git-send-email-srinath.mannam@broadcom.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Ray Jui <ray.jui@broadcom.com>

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