This driver supports the WLED (White LED) functionality of
Qualcomm Technologies PNP PMIC. WLED is used for display backlight.
To compile this driver as a module, choose M here: the module will
be called leds-qpnp-wled.
This driver supports the WLED (White LED) functionality of Qualcomm
Technologies, Inc. QPNP PMICs. WLED is used for LCD backlight with
variable brightness. It also supports outputting the Avdd supply for
AMOLED displays.
