+Properties for an MDIO bus multiplexer controlled by a memory-mapped device
+
+This is a special case of a MDIO bus multiplexer.  A memory-mapped device,
+like an FPGA, is used to control which child bus is connected.  The mdio-mux
+node must be a child of the memory-mapped device.  The driver currently only
+supports devices with eight-bit registers.
+
+Required properties in addition to the generic multiplexer properties:
+
+- compatible : string, must contain "mdio-mux-mmioreg"
+
+- reg : integer, contains the offset of the register that controls the bus
+        multiplexer.  The size field in the 'reg' property is the size of
+        register, and must therefore be 1.
+
+- mux-mask : integer, contains an eight-bit mask that specifies which
+        bits in the register control the actual bus multiplexer.  The
+        'reg' property of each child mdio-mux node must be constrained by
+        this mask.
+
+Example:
+
+The FPGA node defines a memory-mapped FPGA with a register space of 0x30 bytes.
+For the "EMI2" MDIO bus, register 9 (BRDCFG1) controls the mux on that bus.
+A bitmask of 0x6 means that bits 1 and 2 (bit 0 is lsb) are the bits on
+BRDCFG1 that control the actual mux.
