Subject: [PATCH v5 5/6] arm: dts: Change PCIe INTx mapping for HR2
Date:   Thu, 26 Mar 2020 12:18:45 +0530
Message-Id: <1585205326-25326-6-git-send-email-srinath.mannam@broadcom.com>
In-Reply-To: <1585205326-25326-1-git-send-email-srinath.mannam@broadcom.com>
References: <1585205326-25326-1-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.
