+* 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
+
+Driver notifies clients via extcon for VBUS attach/detach
+and charger enable/disable events. Clients registered for these
+notifications should have extcon property set to eud.
+
+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>;
+ };
+
+An example for EUD extcon client:
+
+ usb3 {
+ extcon = <&eud>;
+ };
