    Subject[PATCH 1/4] dt-bingings: PCI: Remove the num-lanes from Required properties
    Date
    From: Hou Zhiqiang <Zhiqiang.Hou@nxp.com>

    The num-lanes is not a mandatory property, e.g. on FSL
    Layerscape SoCs, the PCIe link training is completed
    automatically base on the selected SerDes protocol, it
    doesn't need the num-lanes to set-up the link width.

    It has been added in the Optional properties. This
    patch is to remove it from the Required properties.
