[RFC v5 net-next 05/13] net: mdio: mscc-miim: add ability to externally register phy reset control

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The ocelot-ext driver requires the phys to be externally controlled by an
optional parameter. This commit exposes that variable so it can be
utilized.
