drivers/net/ethernet/smsc/smsc911x.c is expecting supplies named "vdd33a" and "vddvario". Currently the shared DTS file provides "vmmc" and "vmmc_aux", and the supply lookup will fail: smsc911x 2c000000.ethernet: Looking up vdd33a-supply from device tree smsc911x 2c000000.ethernet: Looking up vdd33a-supply property in node /ocp/gpmc@6e000000/ethernet@gpmc failed smsc911x 2c000000.ethernet: Looking up vddvario-supply from device tree smsc911x 2c000000.ethernet: Looking up vddvario-supply property in node /ocp/gpmc@6e000000/ethernet@gpmc failed Fix it! Looks like commmit6b2978ac40(ARM: dts: Shared file for omap GPMC connected smsc911x) made the problem more visible by moving the smc911x configuration from the omap3-igep0020.dts file to the generic file. But it seems we've had this problem since commitd72b441501(ARM: dts: omap3-igep0020: Add SMSC911x LAN chip support). Tested on OMAP3 Overo platform.
