+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: Specifies the external MDIO bus clock speed to
+ be used, if different from the standard 2.5 MHz.
+ This may be due to the standard speed being unsupported (e.g.
+ due to a hardware problem), or to advertise that all relevant
+ components in the system support a faster speed.
+
+- interrupts
+ Usage: required for external MDIO
+ Value type: <prop-encoded-array>
+ Definition: Event interrupt of external MDIO controller.
+
+- fsl,fman-internal-mdio
+ Usage: required for internal MDIO
+ Value type: boolean
+ Definition: Fman 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 be included for internal MDIO.
+
+EXAMPLE
+
+Example for FMan v2 external MDIO:
+
+mdio@f1000 {
+ compatible = "fsl,fman-xmdio";
+ reg = <0xf1000 0x1000>;
+ interrupts = <101 2 0 0>;
+};
+
+Example for FMan v3 internal MDIO:
+
+mdio@f1000 {
+ compatible = "fsl,fman-memac-mdio";
+ reg = <0xf1000 0x1000>;
+ fsl,fman-internal-mdio;
