This patch add a new binding that allows non-PHY MII time stamping
devices to find their buses.  The new documentation covers both the
generic binding and one upcoming user.

Rob might want YAML?

+ZHAW InES PTP time stamping IP core
+
+The IP core needs two different kinds of nodes.  The control node
+lives somewhere in the memory map and specifies the address of the
+control registers.  There can be up to three port handles placed as
+attributes of PHY nodes.  These associate a particular MII bus with a
+port index within the IP core.
+
+Required properties of the control node:
+
+- compatible:		"ines,ptp-ctrl"
+- reg:			physical address and size of the register bank
+
+Required format of the port handle within the PHY node:
+
+- timestamper:		provides control node reference and
+			the port channel within the IP core
+
+Example:
+
+	tstamper: timestamper@60000000 {
+		compatible = "ines,ptp-ctrl";
+		reg = <0x60000000 0x80>;
+	};
+
+	ethernet@80000000 {
+		...
+		mdio {
+			...
+			ethernet-phy@3 {
+				...
+				timestamper = <&tstamper 0>;
You should also add this to Documentation/devicetree/bindings/net/ethernet-phy.yaml
