Marvell DSA Switch Device Tree Bindings
---------------------------------------

WARNING: This binding is currently unstable. Do not program it into a
FLASH never to be changed again. Once this binding is stable, this
warning will be removed.

If you need a stable binding, use the old dsa.txt binding.

Marvell Switches are MDIO devices. The following properties should be
placed as a child node of an mdio device.

The properties described here are those specific to Marvell devices.
Additional required and optional properties can be found in dsa.txt.

Required properties:
- compatible		: Should be one of "marvell,mv88e6085" or
			  "marvell,mv88e6190"
- reg			: Address on the MII bus for the switch.

Optional properties:

- reset-gpios		: Should be a gpio specifier for a reset line
- interrupt-parent	: Parent interrupt controller
- interrupts		: Interrupt from the switch
- interrupt-controller	: Indicates the switch is itself an interrupt
			  controller. This is used for the PHY interrupts.
#interrupt-cells = <2>	: Controller uses two cells, number and flag
- eeprom-length		: Set to the length of an EEPROM connected to the
			  switch. Must be set if the switch can not detect
			  the presence and/or size of a connected EEPROM,
			  otherwise optional.
- mdio			: Container of PHY and devices on the switches MDIO
			  bus.
- mdio?		: Container of PHYs and devices on the external MDIO
			  bus. The node must contains a compatible string of
			  "marvell,mv88e6xxx-mdio-external"

Example:

	mdio {
		#address-cells = <1>;
		#size-cells = <0>;
		interrupt-parent = <&gpio0>;
		interrupts = <27 IRQ_TYPE_LEVEL_LOW>;
		interrupt-controller;
		#interrupt-cells = <2>;

		switch0: switch@0 {
			compatible = "marvell,mv88e6085";
			reg = <0>;
			reset-gpios = <&gpio5 1 GPIO_ACTIVE_LOW>;

			mdio {
				#address-cells = <1>;
				#size-cells = <0>;
				switch1phy0: switch1phy0@0 {
					reg = <0>;
					interrupt-parent = <&switch0>;
					interrupts = <0 IRQ_TYPE_LEVEL_HIGH>;
				};
			};
		};
	};

	mdio {
		#address-cells = <1>;
		#size-cells = <0>;
		interrupt-parent = <&gpio0>;
		interrupts = <27 IRQ_TYPE_LEVEL_LOW>;
		interrupt-controller;
		#interrupt-cells = <2>;

		switch0: switch@0 {
			compatible = "marvell,mv88e6390";
			reg = <0>;
			reset-gpios = <&gpio5 1 GPIO_ACTIVE_LOW>;

			mdio {
				#address-cells = <1>;
				#size-cells = <0>;
				switch1phy0: switch1phy0@0 {
					reg = <0>;
					interrupt-parent = <&switch0>;
					interrupts = <0 IRQ_TYPE_LEVEL_HIGH>;
				};
			};

			mdio1 {
				compatible = "marvell,mv88e6xxx-mdio-external";
				#address-cells = <1>;
				#size-cells = <0>;
				switch1phy9: switch1phy0@9 {
					reg = <9>;
				};
			};
		};
	};
