+* 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

+    - 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.
+

+  Micrel ksz9031rnx Data Sheet, Revision 2.1. Dated 11/20/2014.
+  http://www.micrel.com/_PDF/Ethernet/datasheets/KSZ9031RNX.pdf
+
+Notes:
+
+  Note that a previous version of the Micrel ksz9021rl/rn Data Sheet
+  was missing extended register 106 (transmit data pad skews), and
+  incorrectly specified the ps per step as 200ps/step instead of
+  120ps/step. The latest update to this document reflects the latest
+  revision of the Micrel specification even though usage in the kernel
+  still reflects that incorrect document.
