| MSM SuperSpeed USB3.0 SoC controller |
| |
| Required properties : |
| - compatible : should be "qcom,dwc-usb3-msm" |
| - reg : offset and length of the register set in the memory map |
| offset and length of the TCSR register for routing USB |
| signals to either picoPHY0 or picoPHY1. |
| - interrupts: IRQ lines used by this controller |
| - interrupt-names : Required interrupt resource entries are: |
| "irq" : Interrupt for DWC3 core |
| "otg_irq" : Interrupt for DWC3 core's OTG Events |
| - <supply-name>-supply: phandle to the regulator device tree node |
| Required "supply-name" examples are "SSUSB_VDDCX", "SSUSB_1p8", |
| "HSUSB_VDDCX", "HSUSB_1p8", "HSUSB_3p3" and "vbus_dwc3". |
| - qcom,dwc-usb3-msm-dbm-eps: Number of endpoints avaliable for |
| the DBM (Device Bus Manager). The DBM is HW unit which is part of |
| the MSM USB3.0 core (which also includes the Synopsys DesignWare |
| USB3.0 controller) |
| |
| Optional properties : |
| - Refer to "Documentation/devicetree/bindings/arm/msm/msm_bus.txt" for |
| below optional properties: |
| - qcom,msm_bus,name |
| - qcom,msm_bus,num_cases |
| - qcom,msm_bus,active_only |
| - qcom,msm_bus,num_paths |
| - qcom,msm_bus,vectors |
| - interrupt-names : Optional interrupt resource entries are: |
| "hs_phy_irq" : Interrupt from HSPHY for asynchronous events in LPM. |
| This is not used if wakeup events are received externally (e.g. PMIC) |
