-Micrel KSZ9021 Gigabit Ethernet PHY
-
-Some boards require special tuning values, particularly when it comes to
-clock delays.  You can specify clock delay values by adding
-micrel-specific properties to an Ethernet OF device node.
-
-All skew control options are specified in picoseconds.  The minimum
-value is 0, and the maximum value is 3000.
-
-Optional properties:
- - rxc-skew-ps : Skew control of RXC pad
- - rxdv-skew-ps : Skew control of RX CTL pad
- - txc-skew-ps : Skew control of TXC pad
- - txen-skew-ps : Skew control of TX_CTL pad
- - rxd0-skew-ps : Skew control of RX data 0 pad
- - rxd1-skew-ps : Skew control of RX data 1 pad
- - rxd2-skew-ps : Skew control of RX data 2 pad
- - rxd3-skew-ps : Skew control of RX data 3 pad
- - txd0-skew-ps : Skew control of TX data 0 pad
- - txd1-skew-ps : Skew control of TX data 1 pad
- - txd2-skew-ps : Skew control of TX data 2 pad
- - txd3-skew-ps : Skew control of TX data 3 pad
-
-Examples:
-
-	/* Attach to an Ethernet device with autodetected PHY */
-	&enet {
-		rxc-skew-ps = <3000>;
-		rxdv-skew-ps = <0>;
-		txc-skew-ps = <3000>;
-		txen-skew-ps = <0>;
-		status = "okay";
-	};
-
-	/* Attach to an explicitly-specified PHY */
-	mdio {
-		phy0: ethernet-phy@0 {
-			rxc-skew-ps = <3000>;
-			rxdv-skew-ps = <0>;
-			txc-skew-ps = <3000>;
-			txen-skew-ps = <0>;
-			reg = <0>;
-		};
-	};
-	ethernet@70000 {
-		status = "okay";
-		phy = <&phy0>;
