-* Texas Instruments - dp83867 Giga bit ethernet phy
-
-Required properties:
-	- reg - The ID number for the phy, usually a small integer
-	- ti,rx-internal-delay - RGMII Receive Clock Delay - see dt-bindings/net/ti-dp83867.h
-		for applicable values. Required only if interface type is
-		PHY_INTERFACE_MODE_RGMII_ID or PHY_INTERFACE_MODE_RGMII_RXID
-	- ti,tx-internal-delay - RGMII Transmit Clock Delay - see dt-bindings/net/ti-dp83867.h
-		for applicable values. Required only if interface type is
-		PHY_INTERFACE_MODE_RGMII_ID or PHY_INTERFACE_MODE_RGMII_TXID
-
-Note: If the interface type is PHY_INTERFACE_MODE_RGMII the TX/RX clock delays
-      will be left at their default values, as set by the PHY's pin strapping.
-      The default strapping will use a delay of 2.00 ns.  Thus
-      PHY_INTERFACE_MODE_RGMII, by default, does not behave as RGMII with no
-      internal delay, but as PHY_INTERFACE_MODE_RGMII_ID.  The device tree
-      should use "rgmii-id" if internal delays are desired as this may be
-      changed in future to cause "rgmii" mode to disable delays.
-
-Optional property:
-	- ti,min-output-impedance - MAC Interface Impedance control to set
-				    the programmable output impedance to
-				    minimum value (35 ohms).
-	- ti,max-output-impedance - MAC Interface Impedance control to set
-				    the programmable output impedance to
-				    maximum value (70 ohms).
-	- ti,dp83867-rxctrl-strap-quirk - This denotes the fact that the
-				    board has RX_DV/RX_CTRL pin strapped in
-				    mode 1 or 2. To ensure PHY operation,
-				    there are specific actions that
-				    software needs to take when this pin is
-				    strapped in these modes. See data manual
-				    for details.
-	- ti,clk-output-sel - Muxing option for CLK_OUT pin.  See dt-bindings/net/ti-dp83867.h
-			      for applicable values.  The CLK_OUT pin can also
-			      be disabled by this property.  When omitted, the
-			      PHY's default will be left as is.
-	- ti,sgmii-ref-clock-output-enable - This denotes which
-				    SGMII configuration is used (4 or 6-wire modes).
-				    Some MACs work with differential SGMII clock.
-				    See data manual for details.
-
-	- ti,fifo-depth - Transmitt FIFO depth- see dt-bindings/net/ti-dp83867.h
-		for applicable values (deprecated)
-
-	-tx-fifo-depth - As defined in the ethernet-controller.yaml.  Values for
-			 the depth can be found in dt-bindings/net/ti-dp83867.h
-	-rx-fifo-depth - As defined in the ethernet-controller.yaml.  Values for
-			 the depth can be found in dt-bindings/net/ti-dp83867.h
-
-Note: ti,min-output-impedance and ti,max-output-impedance are mutually
-      exclusive. When both properties are present ti,max-output-impedance
-      takes precedence.
-
-Default child nodes are standard Ethernet PHY device
-nodes as described in Documentation/devicetree/bindings/net/phy.txt
-
-Example:
-
-	ethernet-phy@0 {
-		reg = <0>;
-		ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_25_NS>;
-		ti,tx-internal-delay = <DP83867_RGMIIDCTL_2_75_NS>;
-		tx-fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
-	};

+description: |
+  The DP83867 device is a robust, low power, fully featured Physical Layer
+  transceiver with integrated PMD sublayers to support 10BASE-Te, 100BASE-TX
+  and 1000BASE-T Ethernet protocols.
+
+  The DP83867 is designed for easy implementation of 10/100/1000 Mbps Ethernet
+  LANs. It interfaces directly to twisted pair media via an external
+  transformer. This device interfaces directly to the MAC layer through the
+  IEEE 802.3 Standard Media Independent Interface (MII), the IEEE 802.3 Gigabit
+  Media Independent Interface (GMII) or Reduced GMII (RGMII).
+
+  Specifications about the charger can be found at:
+    https://www.ti.com/lit/gpn/dp83867ir
