help
This driver supports the LPG (Light Pulse Generator) module found in
Qualcomm Technologies, Inc. PMIC chips. Each LPG channel can be
configured to operate in PWM mode to output a fixed amplitude with
variable duty cycle or in LUT (Look up table) mode to output PWM
signal with a modulated amplitude.
