167 | This module provides a driver for MDIO bus multiplexers that | ||
168 | are controlled via a simple memory-mapped device, like an FPGA. | ||
169 | The multiplexer connects one of several child MDIO busses to a | ||
170 | parent bus. Child bus selection is under the control of one of | ||
171 | the FPGA's registers. | ||
172 | |||
173 | Currently, only 8-bit registers are supported. | ||
