X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b1114c1a7a2b3ea2602d30d116cd6d72483659a2;p=openwrt%2Fstaging%2Fjow.git

kernel: add mdio-bus-mux support

The MDIO bus multiplexing framework is used by some drivers
such as dwmac-sun8i.

As this is a per-driver requirement, set it to be hidden in the menu.
