This driver supports flash LED peripheral that is present on
some Qualcomm Technologies, Inc. PMICs (e.g. PM8350C). It can
configure the flash LED target current for several independent
channels. It also supports various over current and over
temperature mitigation features.
To compile this driver as a module, choose M here: the
module will be called leds-qti-flash.
