7 title: Properties for an MDIO bus multiplexer consumer device
10 - Andrew Lunn <andrew@lunn.ch>
13 This is a special case of MDIO mux when MDIO mux is defined as a consumer
14 of a mux producer device. The mux producer can be of any type like mmio mux
15 producer, gpio mux producer or generic register based mux producer.
