1 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
10 - compatible : string, must contain "mdio-mux-mmioreg"
18 'reg' property of each child mdio-mux node must be constrained by
24 For the "EMI2" MDIO bus, register 9 (BRDCFG1) controls the mux on that bus.
