* 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"
|
|
- interrupt-names: Should be "eud_irq"
|
|
- interrupts: Interrupt number
|
|
- reg: Should be address and size of EUD register space
|
|
- reg-names: Should be "eud_base"
|
|
|
|
Optional properties:
|
|
- reg-names: Can be "eud_mode_mgr2" for secure eud
|
|
- qcom,secure-eud-en: To enable secure eud
|
|
- qcom,eud-clock-vote-req: To enable clock voting from eud
|
|
|
|
Driver notifies clients via extcon for VBUS spoof 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";
|
|
interrupt-names = "eud_irq";
|
|
interrupts = <GIC_SPI 492 IRQ_TYPE_LEVEL_HIGH>;
|
|
reg = <0x88e0000 0x4000>;
|
|
reg-names = "eud_base";
|
|
};
|
|
|
|
An example for EUD extcon client:
|
|
|
|
usb3 {
|
|
extcon = <&eud>;
|
|
};
