Some Qualcomm Technologies, Inc. SoCs utilize reference bias generators for

various internal PHY blocks.  These are called REFGENs.



Supported properties:

- compatible

	Usage:      required

	Value type: <string>

	Definition: Must be one of: "qcom,refgen-regulator",

		    "qcom,refgen-sdm845-regulator", or

		    "qcom,refgen-kona-regulator".



- reg

	Usage:      required

	Value type: <prop-encoded-array>

	Definition: Address and size of the REFGEN registers.



- regulator-name

	Usage:      required

	Value type: <string>

	Definition: Specifies the name for this REFGEN regulator.



- regulator-enable-ramp-delay

	Usage:      optional

	Value type: <u32>

	Definition: REFGEN enable time in microseconds.



- parent-supply

	Usage:      optional

	Value type: <phandle>

	Definition: phandle to the parent supply/regulator node if one exists.



Example:



refgen-regulator@ff1000 {

	compatible = "qcom,refgen-regulator";

	reg = <0xff1000 0x60>;

	regulator-name = "refgen";

};
