>Subject: [PATCH v2] armv8: layerscape: Manage PCIe EP compatible string via
>Kconfig
>
>The ep node device tree name is governed by these bindings:
>https://github.com/torvalds/linux/blob/master/Documentation/
>devicetree/bindings/pci/layerscape-pci.txt#L24
>
>As per above the ep compatible node contains platform name.
>Therefore, define the ep node compatible as CONFIG to find the pcie ep node
>in device tree during device tree fixup.
