Documentation for Embedded USB Debugger (EUD) device tree bindings.

I asked questions on v2 which were never answered.

HI Rob,

Can you please review my replies against your comments on patchset v2?

+* Qualcomm Technologies Inc Embedded USB Debugger (EUD)
+
+The EUD (Embedded USB Debugger) is a mini-USB hub implemented
+on chip to support the USB-based debug and trace capabilities.
+
+Required properties:
+
+ - compatible:  Should be "qcom,msm-eud"
+ - interrupts:  Interrupt number
+ - reg: Should be address and size of EUD register space
+
+EUD notifies clients for VBUS attach/detach and charger enable/disable
+events. The link between client and EUD is established via a directed
+graph. EUD has one endpoint of the graph link mentioning EUD as an
+output link and clients of EUD should have the other endpoint of the
+graph link as an input link.
+
+An example for EUD device node:
+
+	eud: qcom,msm-eud@88e0000 {
+		compatible = "qcom,msm-eud";
+		interrupts = <GIC_SPI 492 IRQ_TYPE_LEVEL_HIGH>;
+		reg = <0x88e0000 0x4000>;
+		usb_con: connector {
+                compatible = "usb-c-connector";
+                label = "USB-C";
+                port {
+                	    eud_usb_output: endpoint {
+                        	    remote-endpoint = <&eud_usb3_input>;
+                        };
+        	    };
+        };
+	};
+
+An example for EUD client:
+
+	usb3 {
+		port {
+                eud_usb3_input: endpoint {
+                        remote-endpoint = <&eud_usb_output>;
+                };
+        };
+	};
