haptics ISC (short circuit current) config during LRA impedance
detection.
- qcom,hpwr-supply:
Usage: optional
Value type: <phandle>
Definition: Phandle of the regulator device that supplies power for haptics
module. This is needed when haptics module is supplied by
non-HBoost regulator.
- qcom,hpwr-voltage-mv:
Usage: optional
Value type: <u32>
Definition: Specify the voltage level in mv unit requested from the
non-HBoost regulator. When BoB regulator is used, the
requested voltage shouldn't be higher than 4000 mV.
The following properties are only required when LRA actuator is used:
