+SMSC LAN87xx Ethernet PHY
+
+Some boards require special tuning values. Configure them
+through an Ethernet OF device node.
+
+Optional properties:
+
+- clocks:
+ The clock used as phy reference clock and is connected to phy
+ pin XTAL1/CLKIN.
+
+- smsc,disable-energy-detect:
+ If set, do not enable energy detect mode for the SMSC phy.
+ default: enable energy detect mode
+
+Examples:
+smsc phy with disabled energy detect mode on an am335x based board.
