| * 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" |
| - clocks: a list of phandles to the PHY clocks. Use as per |
| Documentation/devicetree/bindings/clock/clock-bindings.txt |
| - clock-names: Names of the clocks in 1-1 correspondence with |
| the "clocks" property. |
| - <supply-name>-supply: phandle to the regulator device tree node |
| Required "supply-name" examples are: |
| "vdda33" : 3.3v supply to 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"; |
| clocks = <&clock_gcc GCC_USB_PHY_CFG_AHB2PHY_CLK>; |
| clock-names = "cfg_ahb_clk"; |
| vdda33-supply = <&pm8998_l24>; |
| }; |
| |
| An example for EUD extcon client: |
| |
| usb3 { |
| extcon = <&eud>; |
| }; |
