From 49bf9279cd3edb9d7178223f52d4656dbf2e46b5 Mon Sep 17 00:00:00 2001 From: Andrey Smirnov Date: Mon, 25 Jul 2016 21:30:10 -0700 Subject: [PATCH] powerpc/e8248e: Select PHYLIB only if NETDEVICES is enabled Select PHYLIB only if NETDEVICES is enabled and MDIO_BITBANG only if PHYLIB is present to avoid warnings from Kconfig. To prevent undefined references during linking register MDIO driver only if CONFIG_MDIO_BITBANG is enabled.
