Subject: [PATCH v4 12/12] ARM: dts: armada-385.dtsi: Add definitions for PCIe legacy INTx interrupts
Date:   Tue, 22 Feb 2022 16:50:30 +0100
Message-Id: <20220222155030.988-13-pali@kernel.org>
In-Reply-To: <20220222155030.988-1-pali@kernel.org>
References: <20220222155030.988-1-pali@kernel.org>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Precedence: bulk

With this change legacy INTA, INTB, INTC and INTD interrupts are reported
separately and not mixed into one Linux virq source anymore.
