-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, 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>;
