+
+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:
+

+        reg = <0xf1000 0x1000>;

+ *
+ * @num:        The number corresponding to the domain as given in

+ *
+ * @index_kind: A stringifiable token describing the meaning of the index
+ *              within the given domain. Must fit the parsing rules of the
+ *              perf sysfs api.
+ *
+ * @is_physical: True if the domain is physical, false otherwise (if virtual).
+ *
+ * Note: The terms PHYS_CHIP, PHYS_CORE, VCPU correspond to physical chip,
+ *       physical core and virtual processor in 24x7 Counters specifications.
