QPNP (Qualcomm Technologies Inc. Plug N Play) Flash LED (Light
Emitting Diode) driver v2 is used to provide illumination to
camera sensor when background light is dim to capture good
picture. It can also be used for flashlight/torch application.
It is part of PMIC on Qualcomm Technologies Inc. reference platforms.
