+FMan MDIO Node
+
+DESCRIPTION
+
+The MDIO is a bus to which the PHY devices are connected.
+
+PROPERTIES
+
+- compatible
+ Usage: required
+ Value type: <stringlist>
+ Definition: A standard property.
+ Must include "fsl,fman-mdio" for 1 Gb/s MDIO from FMan v2.
+ Must include "fsl,fman-xmdio" for 10 Gb/s MDIO from FMan v2.
+ Must include "fsl,fman-memac-mdio" for 1/10 Gb/s MDIO from
+ FMan v3.
+
+- reg
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: A standard property.
+
+- bus-frequency
+ Usage: optional
+ Value type: <u32>
+ Definition: Default MDIO bus clock speed.
+
+- interrupts
+ Usage: optional
+ Value type: <prop-encoded-array>
+ Definition: MDIO controller event interrupts.
+
+- type
+ Usage: required for FMan v3
+ Value type: <stringlist>
+ Definition: A standard property.
+ FMan v3 has internal MDIO for internal PCS(Physical Coding
+ Sublayer) PHYs and external MDIO for external PHYs.
+ The settings and programming routines for internal/external
+ MDIO are different. Must include "internal" for internal MDIO,
+ must include "external" for external MDIO.
+
+EXAMPLE
+
+Example for FMan v2:
+
+mdio@f1000 {
+ compatible =3D "fsl,fman-xmdio";
+ reg =3D <0xf1000 0x1000>;
+};
+
+Example for FMan v3:
+
+mdio@fd000 {
+ compatible =3D "fsl,fman-memac-mdio";
+ reg =3D <0xfd000 0x1000>;
+ bus-frequency =3D <2500000>;
+ type =3D "external";
+};
