          This driver supports the flash V2 LED functionality of Qualcomm

          Technologies, Inc. QPNP PMICs.  This driver supports PMICs starting

          from PMI8998, PM8150L and their derivatives.  It can configure the

          flash LED target current for several independent channels.  It also

          supports various over current and over temperature mitigation features.
