Note that this symbol cannot be selected by the user, only indirectly via the MDIO_BUS_MUX_GPIO symbol (in patch 3/3) which has the proper dependencies. If we were to specify the dependencies in both places, we gain nothing other than duplication of information. However, if you insist, I will of course add it here too. David Daney
