lx2160 rev1 use mobivel PCIe controller and switch to designware PCIe
controller at rev2, which is mass production version. So drop unused
document.

-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.

-

- compatible = "fsl,lx2160a-pcie";

- reg-names = "csr_axi_slave", "config_axi_slave";
