-* Freescale i.MX6 PCIe interface
-
-This PCIe host controller is based on the Synopsys DesignWare PCIe IP
-and thus inherits all the common properties defined in designware-pcie.txt.
-
-Required properties:
-- compatible:
- - "fsl,imx6q-pcie"
- - "fsl,imx6sx-pcie",
- - "fsl,imx6qp-pcie"
- - "fsl,imx7d-pcie"
- - "fsl,imx8mq-pcie"
-- reg: base address and length of the PCIe controller
-- interrupts: A list of interrupt outputs of the controller. Must contain an
- entry for each entry in the interrupt-names property.
-- interrupt-names: Must include the following entries:
- - "msi": The interrupt that is asserted when an MSI is received
-- clock-names: Must include the following additional entries:
- - "pcie_phy"
-
-Optional properties:
-- fsl,tx-deemph-gen1: Gen1 De-emphasis value. Default: 0
-- fsl,tx-deemph-gen2-3p5db: Gen2 (3.5db) De-emphasis value. Default: 0
-- fsl,tx-deemph-gen2-6db: Gen2 (6db) De-emphasis value. Default: 20
-- fsl,tx-swing-full: Gen2 TX SWING FULL value. Default: 127
-- fsl,tx-swing-low: TX launch amplitude swing_low value. Default: 127
-- fsl,max-link-speed: Specify PCI gen for link capability. Must be '2' for
- gen2, otherwise will default to gen1. Note that the IMX6 LVDS clock outputs
- do not meet gen2 jitter requirements and thus for gen2 capability a gen2
- compliant clock generator should be used and configured.
-- phys: Phandle of the Generic PHY to the PCIe PHY.
-- phy-names: MUST be "pcie-phy".
-- reset-gpio: Should specify the GPIO for controlling the PCI bus device reset
- signal. It's not polarity aware and defaults to active-low reset sequence
- (L=reset state, H=operation state).
-- reset-gpio-active-high: If present then the reset sequence using the GPIO
- specified in the "reset-gpio" property is reversed (H=reset state,
- L=operation state).
-- vpcie-supply: Should specify the regulator in charge of PCIe port power.
- The regulator will be enabled when initializing the PCIe host and
- disabled either as part of the init process or when shutting down the
- host.
-- vph-supply: Should specify the regulator in charge of VPH one of the three
- PCIe PHY powers. This regulator can be supplied by both 1.8v and 3.3v voltage
- supplies.
-
-Additional required properties for imx6sx-pcie:
-- clock names: Must include the following additional entries:
- - "pcie_inbound_axi"
-- power-domains: Must be set to phandles pointing to the DISPLAY and
- PCIE_PHY power domains
-- power-domain-names: Must be "pcie", "pcie_phy"
-
-Additional required properties for imx7d-pcie and imx8mq-pcie:
-- power-domains: Must be set to a phandle pointing to PCIE_PHY power domain
-- resets: Must contain phandles to PCIe-related reset lines exposed by SRC
- IP block
-- reset-names: Must contain the following entries:
- - "pciephy"
- - "apps"
- - "turnoff"
-- fsl,imx7d-pcie-phy: A phandle to an fsl,imx7d-pcie-phy node.
-
-Additional required properties for imx8mq-pcie:
-- clock-names: Must include the following additional entries:
- - "pcie_aux"
-

One patch for this please.
Also, there's now a schema for DW PCI in my tree, so this should be
based on that.
