-MediaTek MT7621 PCIe controller
-
-Required properties:
-- compatible: "mediatek,mt7621-pci"
-- device_type: Must be "pci"
-- reg: Base addresses and lengths of the PCIe subsys and root ports.
-- bus-range: Range of bus numbers associated with this controller.
-- #address-cells: Address representation for root ports (must be 3)
-- pinctrl-names : The pin control state names.
-- pinctrl-0: The "default" pinctrl state.
-- #size-cells: Size representation for root ports (must be 2)
-- ranges: Ranges for the PCI memory and I/O regions.
-- #interrupt-cells: Must be 1
-- interrupt-map-mask and interrupt-map: Standard PCI IRQ mapping properties.
-  Please refer to the standard PCI bus binding document for a more detailed
-  explanation.
-- status: either "disabled" or "okay".
-- resets: Must contain an entry for each entry in reset-names.
-  See ../reset/reset.txt for details.
-- reset-names: Must be "pcie0", "pcie1", "pcieN"... based on the number of
-  root ports.
-- clocks: Must contain an entry for each entry in clock-names.
-  See ../clocks/clock-bindings.txt for details.
-- clock-names: Must be "pcie0", "pcie1", "pcieN"... based on the number of
-  root ports.
-- reset-gpios: GPIO specs for the reset pins.
-
-In addition, the device tree node must have sub-nodes describing each PCIe port
-interface, having the following mandatory properties:
-
-Required properties:
-- reg: Only the first four bytes are used to refer to the correct bus number
-      and device number.
-- #address-cells: Must be 3
-- #size-cells: Must be 2
-- ranges: Sub-ranges distributed from the PCIe controller node. An empty
-  property is sufficient.
-- bus-range: Range of bus numbers associated with this port.
