Common MDIO bus properties.
These are generic properties that can apply to any MDIO bus.
Optional properties:
- reset-gpios: One GPIO that control the RESET lines of all PHYs on that MDIO
bus.
- reset-delay-us: RESET pulse width in microseconds.
A list of child nodes, one per device on the bus is expected. These
should follow the generic phy.txt, or a device specific binding document.
The 'reset-delay-us' indicates the RESET signal pulse width in microseconds and
applies to all PHY devices. It must therefore be appropriately determined based
on all PHY requirements (maximum value of all per-PHY RESET pulse widths).
Example :
This example shows these optional properties, plus other properties
required for the TI Davinci MDIO driver.
davinci_mdio: ethernet@5c030000 {
compatible = "ti,davinci_mdio";
reg = <0x5c030000 0x1000>;
#address-cells = <1>;
#size-cells = <0>;
reset-gpios = <&gpio2 5 GPIO_ACTIVE_LOW>;
reset-delay-us = <2>;
ethphy0: ethernet-phy@1 {
reg = <1>;
};
ethphy1: ethernet-phy@3 {
reg = <3>;
};
};
