    Subject[PATCH 0/6] ARM: dts: pci-mvebu: Fix assigned-addresses for every PCIe Root Port
    Date
    Per IEEE Std 1275-1994 bindings documentation (to which kernel DT
    bindings refers), DT property assigned-addresses contains BDF address
    of resource. Currently more PCIe Root Port nodes have BDF address in
    assigned-addresses which points to different PCIe Root Port nodes. This
    obviously does not make sense as the address resource specified in
    assigned-addresses of every PCIe Root Port describes address range of
    internal registers which are specific for corresponding Marvell PCIe
    Root Port. Fix this issue and align all BDF addresses in
    assigned-addresses DT property to specify correct BDF address of the
    current PCIe Root Port.

    Note that current version of pci-mvebu.c controller driver, which
    registers Marvell PCIe Root Ports, ignores BDF value in DT property
    assigned-addresses. It expects that Root Port's assigned-addresses
    contains address range of that root port. That is why driver currently
    works without any issue and nobody spotted it. But if driver or
    something else would do device tree validation then this issue should be
    spotted and throws error. Also device tree files may be used by other
    projects where drivers may require correct values.

    This patch series aligns BDF address of every Marvell PCIe Root Port in
    node name, config space in reg property and mem in assigned-address
    property of internal registers resource.
