-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 */

-* Mobiveil AXI PCIe Root Port Bridge DT description
-
-Mobiveil's GPEX 4.0 is a PCIe Gen4 root port bridge IP. This configurable IP
-has up to 8 outbound and inbound windows for the address translation.
-
-Required properties:
-- #address-cells: Address representation for root ports, set to <3>
-- #size-cells: Size representation for root ports, set to <2>
-- #interrupt-cells: specifies the number of cells needed to encode an
-	interrupt source. The value must be 1.
-- compatible: Should contain "mbvl,gpex40-pcie"
-- reg: Should contain PCIe registers location and length
-	Mandatory:
-	"config_axi_slave": PCIe controller registers
-	"csr_axi_slave"	  : Bridge config registers
-	Optional:
-	"gpio_slave"	  : GPIO registers to control slot power
-	"apb_csr"	  : MSI registers
-
-- device_type: must be "pci"
-- apio-wins : number of requested apio outbound windows
-		default 2 outbound windows are configured -
-		1. Config window
-		2. Memory window
-- ppio-wins : number of requested ppio inbound windows
-		default 1 inbound memory window is configured.
-- bus-range: PCI bus numbers covered
-- interrupt-controller: identifies the node as an interrupt controller
-- #interrupt-cells: specifies the number of cells needed to encode an
-	interrupt source. The value must be 1.
-- interrupts: The interrupt line of the PCIe controller
-		last cell of this field is set to 4 to
-		denote it as IRQ_TYPE_LEVEL_HIGH type interrupt.
-- interrupt-map-mask,
-	interrupt-map: standard PCI properties to define the mapping of the
-	PCI interface to interrupt numbers.
-- ranges: ranges for the PCI memory regions (I/O space region is not
-	supported by hardware)
-	Please refer to the standard PCI bus binding document for a more
-	detailed explanation
