Subject: [PATCH 1/3] dt-bindings: designware-pcie: document optional msi-parent property
Date: Tue, 30 Aug 2016 14:57:08 +0200 [thread overview]
Message-ID: <1472561830-20932-2-git-send-email-thomas.petazzoni@free-electrons.com> (raw)
In-Reply-To: <1472561830-20932-1-git-send-email-thomas.petazzoni@free-electrons.com>
This commit updates the Designware PCIe Device Tree binding
documentation to document the optional msi-parent property. This
property allows to point to an external MSI controller, which can
optionally be provided. If provided, this external MSI controller is
used in preference over the internal MSI controller of the Designware
PCIe IP.
