-Freescale Layerscape PCIe controller
-
-This PCIe host controller is based on the Synopsys DesignWare PCIe IP
-and thus inherits all the common properties defined in snps,dw-pcie.yaml.
-
-This controller derives its clocks from the Reset Configuration Word (RCW)
-which is used to describe the PLL settings at the time of chip-reset.
-
-Also as per the available Reference Manuals, there is no specific 'version'
-register available in the Freescale PCIe controller register set,
-which can allow determining the underlying DesignWare PCIe controller version
-information.
-
-Required properties:
-- compatible: should contain the platform identifier such as:
-  RC mode:
-        "fsl,ls1021a-pcie"
-        "fsl,ls2080a-pcie", "fsl,ls2085a-pcie"
-        "fsl,ls2088a-pcie"
-        "fsl,ls1088a-pcie"
-        "fsl,ls1046a-pcie"
-        "fsl,ls1043a-pcie"
-        "fsl,ls1012a-pcie"
-        "fsl,ls1028a-pcie"
-  EP mode:
-	"fsl,ls1028a-pcie-ep", "fsl,ls-pcie-ep"
-	"fsl,ls1046a-pcie-ep", "fsl,ls-pcie-ep"
-	"fsl,ls1088a-pcie-ep", "fsl,ls-pcie-ep"
-	"fsl,ls2088a-pcie-ep", "fsl,ls-pcie-ep"
-	"fsl,lx2160ar2-pcie-ep", "fsl,ls-pcie-ep"
-- reg: base addresses and lengths of the PCIe controller register blocks.
-- 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:
-  "aer": Used for interrupt line which reports AER events when
-	 non MSI/MSI-X/INTx mode is used
-  "pme": Used for interrupt line which reports PME events when
-	 non MSI/MSI-X/INTx mode is used
-  "intr": Used for SoCs(like ls2080a, lx2160a, ls2080a, ls2088a, ls1088a)
-	  which has a single interrupt line for miscellaneous controller
-	  events(could include AER and PME events).
-- fsl,pcie-scfg: Must include two entries.
-  The first entry must be a link to the SCFG device node
-  The second entry is the physical PCIe controller index starting from '0'.
-  This is used to get SCFG PEXN registers
-- 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.
-
-Optional properties:
-- big-endian: If the PEX_LUT and PF register block is in big-endian, specify
-  this property.
