Qualcomm Technologies, Inc. Vibrator-LDO



QPNP (Qualcomm Technologies, Inc. Plug N Play) Vibrator-LDO is a peripheral

on some QTI PMICs. It can be interfaced with the host processor via SPMI.



Vibrator-LDO peripheral supports Eccentric Rotation Mass (ERM) vibrator.



Properties:



- compatible

	Usage:      required

	Value type: <string>

	Definition: "qcom,qpnp-vibrator-ldo".



- reg

	Usage:      required

	Value type: <u32>

	Definition: Base address of vibrator-ldo peripheral.



- qcom,vib-ldo-volt-uv

	Usage:      required

	Value type: <u32>

	Definition: The optimal voltage requirement of the vibrator motor for

		    a normal vibration. Value is specified in microvolts.



- qcom,disable-overdrive

	Usage:      optional

	Value type: <empty>

	Definition: Do not apply overdrive voltage.



- qcom,vib-overdrive-volt-uv

	Usage:      optional and not required if qcom,disable-overdrive present

	Value type: <u32>

	Definition: The voltage in microvolts used as overdrive factor for

		    improving motor reactivity at the start of vibration.

		    If this property not specified, a default value of

		    2 times the value specified in qcom,vib-ldo-volt-uv

		    property is used.
