Subject: [PATCH v2 02/10] ARM: dts: dove: Add definitions for PCIe legacy INTx interrupts
Date: Tue, 12 Jul 2022 18:41:00 +0200 [thread overview]
Message-ID: <20220712164108.30262-3-kabel@kernel.org> (raw)
In-Reply-To: <20220712164108.30262-1-kabel@kernel.org>
From: Pali Rohár <pali@kernel.org>
Add definitions for PCIe legacy INTx interrupts.
This is required for example in a scenario where a driver requests only
one of the legacy interrupts (INTA). Without this, the driver would be
notified on events on all 4 (INTA, INTB, INTC, INTD), even if it
requested only one of them.
