+* TSEC-compatible ethernet nodes
+
+Properties:
+
+ - compatible : Should be "fsl,tsec"
+ - reg : Offset and length of the register set for the device
+ - phy-handle : See ethernet.txt file in the same directory.
+ - phy-connection-type : See ethernet.txt file in the same directory. This
+ property is only really needed if the connection is of type "rgmii-id",
+ "rgmii-rxid" and "rgmii-txid" as all other connection types are detected
+ by hardware.
+
+Example:
+ ethernet@24000 {
+ compatible = "fsl,tsec";
+ reg = <0x24000 0x1000>;
+ phy-handle = <&phy0>;
+ phy-connection-type = "sgmii";
+ };
+
+Child nodes of the TSEC controller are typically the individual PHY devices
+connected via the MDIO bus (sometimes the MDIO bus controller is separate).
+
+* MDIO IO device
+
+The MDIO is a bus to which the PHY devices are connected. For each
+device that exists on this bus, a PHY node should be created.
+
+Required properties:
+ - compatible : Should define the compatible device type for the
+ mdio. Currently supported string/device is "fsl,tsec-mdio".
+ - reg : Offset and length of the register set for the device
+
+Example:
+
+ mdio@24520 {
+ compatible = "fsl,tsec-mdio";
+ reg = <0x24520 0x20>;
+
+ ethernet-phy@0 {
+ reg = <0>;
+ };
+ };
+
+* TBI Internal MDIO bus
+
+As of this writing, every tsec is associated with an internal TBI PHY.
+This PHY is accessed through the local MDIO bus. These buses are defined
+similarly to the mdio buses. The TBI PHYs underneath them are similar to
+normal PHYs, but the reg property is considered instructive, rather than
+descriptive. The reg property should be chosen so it doesn't interfere
+with other PHYs on the bus. The TBI PHYs are referred to by a "tbi-handle"
+property under the tsec node, which has a similar meaning of "phy-handle".
+
+Example:
+ ethernet@24000 {
+ phy-handle = <&tbi1>;
+ };
+
+ mdio@24520 {
+ tbi1: tbi-phy@1f {
+ reg = <0x1f>;
+ };
+ };

+Micrel KSZ9021/KSZ9031 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.
+
+Note that these settings are applied after any phy-specific fixup from
+phy_fixup_list (see phy_init_hw() from drivers/net/phy/phy_device.c),
+and therefore may overwrite them.
+
+KSZ9021:
+
+ All skew control options are specified in picoseconds. The minimum
+ value is 0, the maximum value is 1800, and it is incremented by 120ps
+ steps.
+
+ 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
+
+KSZ9031:
+
+ All skew control options are specified in picoseconds. The minimum
+ value is 0, and the maximum is property-dependent. The increment
+ step is 60ps.
+
+ The KSZ9031 hardware supports a range of skew values from negative to
+ positive, where the specific range is property dependent. All values
+ specified in the devicetree are offset by the minimum value so they
+ can be represented as positive integers in the devicetree since it's
+ difficult to represent a negative number in the devictree.
+
+ The following 5-bit values table apply to rxc-skew-ps and txc-skew-ps.
