Merge "usb: phy: Add snapshot of phy-msm-ssusb driver"

Qualcomm Technologies, Inc. MSM PHY Transceivers

Required properties:

- compatible: Should be "qcom,usb-ssphy" or "qcom,usb-ssphy-qmp-v2"

- reg: Address and length of the register set for the device

- <supply-name>-supply: phandle to the regulator device tree node

Required "supply-name" examples are:

"vdd" : vdd supply for SSPHY digital circuit operation

"vdda18" : 1.8v high-voltage analog supply for SSPHY

- qcom,vdd-voltage-level: This property must be a list of three integer

values (no, min, max) where each value represents either a voltage in

microvolts or a value corresponding to voltage corner

Optional properties:

- qcom,vbus-valid-override: If present, indicates VBUS pin is not connected to

the USB PHY and the controller must rely on external VBUS notification in

order to manually relay the notification to the SSPHY.

- qcom,deemphasis-value: This property if present represents ss phy

deemphasis value to be used for overriding into SSPHY register.

- qcom,primary-phy: If present, indicates this is a secondary PHY and is

dependent on the primary PHY referenced by this phandle.

- qcom,override-pll-calibration: If present, program PHY register to overrride

the automatic PHY PLL calibration settings.

- qcom,qmp-misc-config: If present, program PHY miscellaneous device-specific

registers.

Example:

ssphy@f9200000 {

compatible = "qcom,usb-ssphy";

reg = <0xf9200000 0xfc000>;

vdd-supply = <&pm8841_s2_corner>;

vdda18-supply = <&pm8941_l6>;

qcom,vdd-voltage-level = <1 5 7>;

qcom,deemphasis-value = <26>;

};

	  This driver is not supported on boards like trout which

	  has an external PHY.

	  This driver supports the PHY which uses the QSCRATCH-based register

	  set for its control sequences, normally paired with newer DWC3-based

	  SuperSpeed controllers.
