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
|
|
- mdio : container of PHY and devices on the switches MDIO
|
|
bus
|
|
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>;
|
|
};
|
|
};
|
|
};
