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	[thread overview]
Message-ID: <20220222155030.988-13-pali@kernel.org> (raw)
In-Reply-To: <20220222155030.988-1-pali@kernel.org>

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

Signed-off-by: Pali Rohár <pali@kernel.org>
Acked-by: Gregory CLEMENT <gregory.clement@bootlin.com>
Tested-by: Luis Mendes <luis.p.mendes@gmail.com>
