Kernel-4.18.0-80.el8_qcom,usb-hs-phy

Qualcomm’s USB HS PHY

PROPERTIES

• compatible:
  Usage: required
  Value type:
  Definition: Should contain “qcom,usb-hs-phy” and more specifically one of the

            following:
  
                    "qcom,usb-hs-phy-apq8064"
                    "qcom,usb-hs-phy-msm8916"
                    "qcom,usb-hs-phy-msm8974"
  

• #phy-cells:
  Usage: required
  Value type:
  Definition: Should contain 0

• clocks:
  Usage: required
  Value type:
  Definition: Should contain clock specifier for the reference and sleep

            clocks
  

• clock-names:
  Usage: required
  Value type:
  Definition: Should contain “ref” and “sleep” for the reference and sleep

            clocks respectively
  

• resets:
  Usage: required
  Value type:
  Definition: Should contain the phy and POR resets

• reset-names:
  Usage: required
  Value type:
  Definition: Should contain “phy” and “por” for the phy and POR resets

            respectively
  

• v3p3-supply:
  Usage: required
  Value type:
  Definition: Should contain a reference to the 3.3V supply

• v1p8-supply:
  Usage: required
  Value type:
  Definition: Should contain a reference to the 1.8V supply

• extcon:
  Usage: optional
  Value type:
  Definition: Should contain the vbus extcon

• qcom,init-seq:
  Usage: optional
  Value type:
  Definition: Should contain a sequence of ULPI address and value pairs to

            program into the ULPI_EXT_VENDOR_SPECIFIC area. This is related
            to Device Mode Eye Diagram test. The addresses are offsets
            from the ULPI_EXT_VENDOR_SPECIFIC address, for example,
            <0x1 0x53> would mean "write the value 0x53 to address 0x81".
