Hello, This set of patches introduces Message Signaled Interrupt support in the Marvell EBU PCIe driver. It has been successfully tested on the Armada XP GP platform with an Intel e1000e PCIe network card that supports MSI. This version 2 follows the RFC version sent on March, 26th 2013. This is based on work done by Lior Amsalem <alior@xxxxxxxxxxx>. The patches do the following: * Patch 1 comes from Thierry Redding, and adds a minimal msi_chip infrastructure. This needs to be reviewed/acked by Bjorn Helgaas. * Patch 2 extends the msi_chip infrastructure with a small registry, so that one driver can register an msi_chip, and another driver can find the msi_chip associated to a particular Device Tree node. This needs to be reviewed/acked by Bjorn Helgaas. * Patch 3 makes some not very interesting preparation in the Armada 370/XP IRQ controller driver. * Patch 4 implements the MSI support in the Armada 370/XP IRQ controller driver. It registers an msi_chip using the msi_chip_add() function added in PATCH 2. * Patch 5 adjust the Armada 370/XP Device Tree to indicate that the MPIC is not only an interrupt-controller, but also an msi-controller. * Patch 6 adds MSI support in the Marvell PCIe host controller driver. The work to do here is minimal: get a reference to the msi-parent controller thanks to msi_chip_find_by_of_node(), and link it to the pci_bus structure before the bus gets enumerated. This needs to be reviewed/acked by Bjorn Helgaas. * Patch 7 tunes Kconfig to indicate that Armada 370/XP supports MSI. * Patch 8 adjusts the Armada 370/XP Device Tree to add the msi-parent properties in the PCIe controller nodes. This set of patches currently applies on top of the current "for-next" branch of Jason Cooper's repository. The Device Tree binding documentation updates will be added once the general approach is agreed on.
