Subject: [PATCH v4 2/4] dt-bindings: interrupt-controller: msi: Add msi-ranges property
Date: Fri, 27 Aug 2021 19:15:27 +0200 [thread overview]
Message-ID: <20210827171534.62380-3-mark.kettenis@xs4all.nl> (raw)
In-Reply-To: <20210827171534.62380-1-mark.kettenis@xs4all.nl>
From: Mark Kettenis <kettenis@openbsd.org>
Update the MSI controller binding to add an msi-ranges property
that specifies how MSIs map onto regular interrupts on some other
interrupt controller.
