Subject: [PATCH net-next v1] dt-bindings: net: convert qca,ar71xx documentation to yaml

Now that we have the DT validation in place, let's convert the device tree
bindings for the Atheros AR71XX over to a YAML schemas.

-Required properties:
-- compatible:	Should be "qca,<soc>-eth". Currently support compatibles are:
-		qca,ar7100-eth - Atheros AR7100
-		qca,ar7240-eth - Atheros AR7240
-		qca,ar7241-eth - Atheros AR7241
-		qca,ar7242-eth - Atheros AR7242
-		qca,ar9130-eth - Atheros AR9130
-		qca,ar9330-eth - Atheros AR9330
-		qca,ar9340-eth - Atheros AR9340
-		qca,qca9530-eth - Qualcomm Atheros QCA9530
-		qca,qca9550-eth - Qualcomm Atheros QCA9550
-		qca,qca9560-eth - Qualcomm Atheros QCA9560
-
-- reg : Address and length of the register set for the device
-- interrupts : Should contain eth interrupt
-- phy-mode : See ethernet.txt file in the same directory
-- clocks: the clock used by the core
-- clock-names: the names of the clock listed in the clocks property. These are
-	"eth" and "mdio".
-- resets: Should contain phandles to the reset signals
-- reset-names: Should contain the names of reset signal listed in the resets
-		property. These are "mac" and "mdio"
-
-Optional properties:
-- phy-handle : phandle to the PHY device connected to this device.
-- fixed-link : Assume a fixed link. See fixed-link.txt in the same directory.
-  Use instead of phy-handle.
-
-Optional subnodes:
-- mdio : specifies the mdio bus, used as a container for phy nodes
-  according to phy.txt in the same directory
-
-Example:
-
-ethernet@...00000 {
-	compatible = "qca,ar9330-eth";
-	reg = <0x1a000000 0x200>;
-	interrupts = <5>;
-	resets = <&rst 13>, <&rst 23>;
-	reset-names = "mac", "mdio";
-	clocks = <&pll ATH79_CLK_AHB>, <&pll ATH79_CLK_MDIO>;
-	clock-names = "eth", "mdio";
-
-	phy-mode = "gmii";
