dt-bindings: marvell: Rewrite MV88E6xxx in schema



This is an attempt to rewrite the Marvell MV88E6xxx switch bindings
in YAML schema.

The current text binding says:
  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.

Well that never happened before we switched to YAML markup,
we can't have it like this, what about fixing the mess?

		maintainers:

		description:
		The Marvell MV88E6xxx switch series has been produced and sold
		by Marvell since at least 2008. The switch has a few compatibles which
		just indicate the base address of the switch, then operating systems
		can investigate switch ID registers to find out which actual version
		of the switch it is dealing with.

		properties:
		compatible:
		enum:
		- marvell,mv88e6085
		- marvell,mv88e6190
		- marvell,mv88e6250
		description: \|
		marvell,mv88e6085: This switch uses base address 0x10.
		This switch and its siblings will be autodetected from
		ID registers found in the switch, so only "marvell,mv88e6085" should be
		specified. This includes the following list of MV88Exxxx switches:
		6085, 6095, 6097, 6123, 6131, 6141, 6161, 6165, 6171, 6172, 6175, 6176,

		6190, 6190X, 6191, 6290, 6361, 6390, 6390X

		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@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,mv88e6190";
		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>;
		};
		};
		};
