This commit adds the required pin muxing for the network interfaces and the MDIO interface to be properly initialized. For instance, this makes it possible for a bootloader to initialize and access the network interfaces Signed-off-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Acked-by: Andrew Lunn <andrew@lunn.ch> Link: https://lkml.kernel.org/r/1407759281-11513-4-git-send-email-ezequiel.garcia@free-electrons.com Signed-off-by: Jason Cooper <jason@lakedaemon.net>
