Subject: [PATCH 1/2] arm64: dts: marvell: remove msi-parent from PCIe on Armada 3700
Date: Thu,  1 Sep 2016 17:41:23 +0200	[thread overview]
Message-ID: <1472744484-19132-2-git-send-email-thomas.petazzoni@free-electrons.com> (raw)
In-Reply-To: <1472744484-19132-1-git-send-email-thomas.petazzoni@free-electrons.com>

Following the switch of the Aardvark PCIe controller driver to the
generic MSI support, the msi-parent property in the PCIe controller,
pointing to itself is no longer needed: since the MSI irq domain is
associated to the PCIe controller Device Tree node, this is sufficient
for the interrupt resolution logic to work.

Please only apply once "pci: pci-aardvark: move to MSI handling using
generic MSI support" is merged, or it will break MSI support on Armada
3700.
