config INPUT_QCOM_HV_HAPTICS
tristate "QTI High Voltage Haptics support"
depends on MFD_SPMI_PMIC
help
This option enables device driver support for the high voltage haptics
peripheral found on Qualcomm Technologies, Inc. PMICs. The high voltage
haptics peripheral is capable of driving either LRA or ERM vibrators with
drive voltage up to 10 V, and its 5 integrated pattern sources can be used
for playing different vibration effects. To compile this driver as a module,
choose M here: the module will be called qcom-hv-haptics.
