+NXP Layerscape PCIe Gen4 controller
+
+This PCIe controller is based on the Mobiveil PCIe IP and thus inherits all
+the common properties defined in mobiveil-pcie.txt.
+
+Required properties:
+- compatible: should contain the platform identifier such as:
+  "fsl,lx2160a-pcie"
+- reg: base addresses and lengths of the PCIe controller register blocks.
+  "csr_axi_slave": Bridge config registers
+  "config_axi_slave": PCIe controller registers
+- interrupts: A list of interrupt outputs of the controller. Must contain an
+  entry for each entry in the interrupt-names property.
+- interrupt-names: It could include the following entries:
+  "intr": The interrupt that is asserted for controller interrupts
+  "aer": Asserted for aer interrupt when chip support the aer interrupt with
+	 none MSI/MSI-X/INTx mode,but there is interrupt line for aer.
+  "pme": Asserted for pme interrupt when chip support the pme interrupt with
+	 none MSI/MSI-X/INTx mode,but there is interrupt line for pme.
+- dma-coherent: Indicates that the hardware IP block can ensure the coherency
+  of the data transferred from/to the IP block. This can avoid the software
+  cache flush/invalid actions, and improve the performance significantly.
+- msi-parent : See the generic MSI binding described in
+  Documentation/devicetree/bindings/interrupt-controller/msi.txt.
+
+Example:
+
+	pcie@3400000 {
+		compatible = "fsl,lx2160a-pcie";
+		reg = <0x00 0x03400000 0x0 0x00100000   /* controller registers */
+		       0x80 0x00000000 0x0 0x00001000>; /* configuration space */
+		reg-names = "csr_axi_slave", "config_axi_slave";
+		interrupts = <GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH>, /* AER interrupt */
+			     <GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH>, /* PME interrupt */
+			     <GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH>; /* controller interrupt */
+		interrupt-names = "aer", "pme", "intr";
+		#address-cells = <3>;
+		#size-cells = <2>;
+		device_type = "pci";
+		apio-wins = <8>;
+		ppio-wins = <8>;
+		dma-coherent;
+		bus-range = <0x0 0xff>;
+		msi-parent = <&its>;
+		ranges = <0x82000000 0x0 0x40000000 0x80 0x40000000 0x0 0x40000000>;
+		#interrupt-cells = <1>;
+		interrupt-map-mask = <0 0 0 7>;
+		interrupt-map = <0000 0 0 1 &gic 0 0 GIC_SPI 109 IRQ_TYPE_LEVEL_HIGH>,
+				<0000 0 0 2 &gic 0 0 GIC_SPI 110 IRQ_TYPE_LEVEL_HIGH>,
+				<0000 0 0 3 &gic 0 0 GIC_SPI 111 IRQ_TYPE_LEVEL_HIGH>,
+				<0000 0 0 4 &gic 0 0 GIC_SPI 112 IRQ_TYPE_LEVEL_HIGH>;
