Subject: [PATCH v4 12/18] arm: mvebu: add PCIe Device Tree informations for Armada XP
Date: Fri, 8 Mar 2013 16:19:14 +0100 [thread overview]
Message-ID: <1362755960-30791-13-git-send-email-thomas.petazzoni@free-electrons.com> (raw)
In-Reply-To: <1362755960-30791-1-git-send-email-thomas.petazzoni@free-electrons.com>
The Armada XP SoCs have multiple PCIe interfaces. The MV78230 has 2
PCIe units (one 4x or quad 1x, the other 1x only), the MV78260 has 3
PCIe units (two 4x or quad 1x and one 4x/1x), the MV78460 has 4 PCIe
units (two 4x or quad 1x and two 4x/1x). We therefore add the
necessary Device Tree informations to make those PCIe interfaces
usable.
