-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.
-
-The compatibility string is used only to find an identification register,
-which is at a different MDIO base address in different switch families.
-- "marvell,mv88e6085"	: Switch has base address 0x10. Use with models:
-			  6085, 6095, 6097, 6123, 6131, 6141, 6161, 6165,
-			  6171, 6172, 6175, 6176, 6185, 6240, 6320, 6321,
-			  6341, 6350, 6351, 6352
-- "marvell,mv88e6190"	: Switch has base address 0x00. Use with models:
-			  6190, 6190X, 6191, 6290, 6361, 6390, 6390X
-- "marvell,mv88e6250"	: Switch has base address 0x08 or 0x18. Use with model:
-			  6220, 6250
-
-Required properties:
-- compatible		: Should be one of "marvell,mv88e6085",
-			  "marvell,mv88e6190" or "marvell,mv88e6250" as
-			  indicated above
-- reg			: Address on the MII bus for the switch.
-
-Optional properties:
-
-- reset-gpios		: Should be a gpio specifier for a reset line
-- 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 at 0 {
-			compatible = "marvell,mv88e6085";
-			reg = <0>;
-			reset-gpios = <&gpio5 1 GPIO_ACTIVE_LOW>;
-
-			mdio {
-				#address-cells = <1>;
-				#size-cells = <0>;
-				switch1phy0: switch1phy0 at 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 at 0 {
-			compatible = "marvell,mv88e6190";
-			reg = <0>;

-
-			mdio {

-				#size-cells = <0>;
-				switch1phy0: switch1phy0 at 0 {
