1Common MDIO bus properties.
2
3These are generic properties that can apply to any MDIO bus.
4
5Optional properties:
6- reset-gpios: One GPIO that control the RESET lines of all PHYs on that MDIO
7  bus.
8- reset-delay-us: RESET pulse width in microseconds.
9
10A list of child nodes, one per device on the bus is expected. These
11should follow the generic phy.txt, or a device specific binding document.
12
13The 'reset-delay-us' indicates the RESET signal pulse width in microseconds and
14applies to all PHY devices. It must therefore be appropriately determined based
15on all PHY requirements (maximum value of all per-PHY RESET pulse widths).

17Example :
18This example shows these optional properties, plus other properties
19required for the TI Davinci MDIO driver.
20
21	davinci_mdio: ethernet@0x5c030000 {
22		compatible = "ti,davinci_mdio";
23		reg = <0x5c030000 0x1000>;
24		#address-cells = <1>;
25		#size-cells = <0>;
26
27		reset-gpios = <&gpio2 5 GPIO_ACTIVE_LOW>;
28		reset-delay-us = <2>;
29
30		ethphy0: ethernet-phy@1 {
31			reg = <1>;
32		};
33
34		ethphy1: ethernet-phy@3 {
35			reg = <3>;
36		};
37	};
