  The EUD (Embedded USB Debugger) is a mini-USB hub implemented

  on chip to support the USB-based debug and trace capabilities.

properties:

  compatible:

    Usage: required

    Value type: <string>

    Definition: Must be "qcom,msm-eud"

  reg:

    Usage: required

    Value type: <prop-encoded-array>

    Definition: address and size of EUD register space

  reg-names:

    Usage: required

    Value type: <string>

    Definition: Must be "eud_base"

  interrupts:

    Usage: required

    Value type: <prop-encoded-array>

    Definition: Interrupt number

  interrupt-names:

    Usage: required

    Value type: <string>

    Definition: Must be "eud_irq"

  reg-names:

    Usage: optional

    Value type: <string>

    Definition: Must be "eud_mode_mgr2" for secure eud

  qcom,secure-eud-en:

    Usage: optional to enable secure eud

  qcom,eud-clock-vote-req:

    Usage: optional to enable clock voting from eud

example:

  - |

    eud: qcom,msm-eud@88e0000 {

       compatible = "qcom,msm-eud";

       interrupt-names = "eud_irq";

       interrupts = <GIC_SPI 492 IRQ_TYPE_LEVEL_HIGH>;

       reg = <0x88e0000 0x4000>;

       reg-names = "eud_base";

    };

client-example:

  - |

    usb3 {

	extcon = <&eud>;

    };
