[PATCH 1/3] dt-bindings: net: Convert fsl,gianfar-{mdio,tbi} to YAML

[J. Neuschäfer via B4 Relay]

From: "J. Neuschäfer" <j.ne@xxxxxxxxxx>

Move the information related to the Freescale Gianfar (TSEC) MDIO bus
and the Ten-Bit Interface (TBI) from fsl-tsec-phy.txt to a new binding
file in YAML format, fsl,gianfar-mdio.yaml.

+title: Freescale Gianfar (TSEC) MDIO Device
+
+description:
+  This binding describes the MDIO is a bus to which the PHY devices are
+  connected. For each device that exists on this bus, a child node should be
+  created.
+
+  As of this writing, every TSEC is associated with an internal Ten-Bit
+  Interface (TBI) PHY. This PHY is accessed through the local MDIO bus. These
+  buses are defined similarly to the mdio buses, except they are compatible
+  with "fsl,gianfar-tbi". 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.

 * MDIO IO device
 
-The MDIO is a bus to which the PHY devices are connected.  For each
-device that exists on this bus, a child node should be created.  See
-the definition of the PHY node in booting-without-of.txt for an example
-of how to define a PHY.
-
-Required properties:
-  - reg : Offset and length of the register set for the device, and optionally
-          the offset and length of the TBIPA register (TBI PHY address
-	  register).  If TBIPA register is not specified, the driver will
-	  attempt to infer it from the register set specified (your mileage may
-	  vary).
-  - compatible : Should define the compatible device type for the
-    mdio. Currently supported strings/devices are:
-	- "fsl,gianfar-tbi"
-	- "fsl,gianfar-mdio"
-	- "fsl,etsec2-tbi"
-	- "fsl,etsec2-mdio"
-	- "fsl,ucc-mdio"
-	- "fsl,fman-mdio"
-    When device_type is "mdio", the following strings are also considered:
-	- "gianfar"
-	- "ucc_geth_phy"
-
-Example:
-
-	mdio@24520 {
-		reg = <24520 20>;
-		compatible = "fsl,gianfar-mdio";
-
-		ethernet-phy@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, except they are compatible with "fsl,gianfar-tbi".
-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.
