    +* 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 for VBUS attach/detach and charger enable/disable
    +events. The link between client and EUD is established via a directed
    +graph. EUD driver has one endpoint of the graph link mentioning EUD as an
    +output link and clients registered for these notifications from the EUD
    +should have the other endpoint of the graph link as an input link. Each of
    +these endpoints should contain a 'remote-endpoint' phandle property that
    +points to the corresponding endpoint in the port of the remote device.
    +
    +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>;
    + port {
    + eud_output: endpoint {
    + remote-endpoint = <&usb3_input>;
    + };
    + };
    + };
    +
    +An example for EUD client:
    +
    + usb3 {
    + port {
    + usb3_input: endpoint {
    + remote-endpoint = <&eud_output>;
    + };
    + };
    + };
