CONFIG_MDIO_BUS_MUX_MMIOREG: Support for MMIO device-controlled MDIO bus multiplexers

General informations

The Linux kernel configuration item CONFIG_MDIO_BUS_MUX_MMIOREG:

• prompt: Support for MMIO device-controlled MDIO bus multiplexers
• type: tristate
• depends on: CONFIG_OF_MDIO
• defined in drivers/net/phy/Kconfig
• found in Linux kernels: 3.7–3.9, 3.10-rc+HEAD
• modules built: mdio-mux-mmioreg

Help text

This module provides a driver for MDIO bus multiplexers that are controlled via a simple memory-mapped device, like an FPGA. The multiplexer connects one of several child MDIO busses to a parent bus. Child bus selection is under the control of one of the FPGA's registers.

Currently, only 8-bit registers are supported.
