Dmdio-mux-multiplexer.txt1 Properties for an MDIO bus multiplexer consumer device
3 This is a special case of MDIO mux when MDIO mux is defined as a consumer
4 of a mux producer device. The mux producer can be of any type like mmio mux
5 producer, gpio mux producer or generic register based mux producer.
7 Required properties in addition to the MDIO Bus multiplexer properties:
9 - compatible : should be "mmio-mux-multiplexer"
10 - mux-controls : mux controller node to use for operating the mux
11 - mdio-parent-bus : phandle to the parent MDIO bus.

Dmdio-mux-mmioreg.txt1 Properties for an MDIO bus multiplexer controlled by a memory-mapped device
3 This is a special case of a MDIO bus multiplexer. A memory-mapped device,
4 like an FPGA, is used to control which child bus is connected. The mdio-mux
5 node must be a child of the memory-mapped device. The driver currently only
6 supports devices with 8, 16 or 32-bit registers.
8 Required properties in addition to the generic multiplexer properties:
10 - compatible : string, must contain "mdio-mux-mmioreg"
12 - reg : integer, contains the offset of the register that controls the bus
13 multiplexer. The size field in the 'reg' property is the size of

Dbrcm,mdio-mux-iproc.txt1 Properties for an MDIO bus multiplexer found in Broadcom iProc based SoCs.
3 This MDIO bus multiplexer defines buses that could be internal as well as
4 external to SoCs and could accept MDIO transaction compatible to C-22 or
5 C-45 Clause. When child bus is selected, one needs to select these two
6 properties as well to generate desired MDIO transaction on appropriate bus.
8 Required properties in addition to the generic multiplexer properties:
10 MDIO multiplexer node:
11 - compatible: brcm,mdio-mux-iproc.
13 Every non-ethernet PHY requires a compatible so that it could be probed based

5 MDIO bus.
7 Required properties in addition to the generic multiplexer properties:
8 - compatible : amlogic,g12a-mdio-mux
9 - reg: physical address and length of the multiplexer/glue registers
10 - clocks: list of clock phandle, one for each entry clock-names.
