+Properties for an MDIO bus multiplexer consumer device
+
+This is a special case of MDIO mux when MDIO mux is defined as a consumer
+of a mux producer device. The mux producer can be of any type like mmio mux
+producer, gpio mux producer or generic register based mux producer.
+
+Required properties in addition to the MDIO Bus multiplexer properties:
+
+- compatible : should be "mmio-mux-multiplexer"
+- mux-controls : mux controller node to use for operating the mux
+- mdio-parent-bus : phandle to the parent MDIO bus.
+
+each child node of mdio bus multiplexer consumer device represent a mdio
+bus.
+
+for more information please refer
+Documentation/devicetree/bindings/mux/mux-controller.txt
+and Documentation/devicetree/bindings/net/mdio-mux.txt
+
+Example:
+In below example the Mux producer and consumer are separate nodes.

+ fpga@66 { // fpga connected to i2c
+ compatible = "fsl,lx2160aqds-fpga", "fsl,fpga-qixis-i2c",
