Subject: [PATCH v1 1/7] PCI: dt: Add legacy PCI IRQ defines
Date: Mon, 4 Nov 2019 16:38:15 +0000 [thread overview]
Message-ID: <20191104163834.8932-2-andrew.murray@arm.com> (raw)
In-Reply-To: <20191104163834.8932-1-andrew.murray@arm.com>
PCI devices can trigger interrupts via 4 physical/virtual lines known
as INTA, INTB, INTC or INTD. Due to interrupt swizzling it is often
required to describe the interrupt mapping in the device tree. Let's
add a define for each type to improve device tree clarity.
