Subject: [PATCH v4 23/29] pci: layerscape: add official ls1028a
binding
support
The official bindind of the PCIe controller of the ls1028a has the
following
compatible string:
compatible = "fsl,ls1028a-pcie";
Additionally, the resource names and count are different. Update the
driver
to support this binding and change the entry in the ls1028a device
tree.
