13 Flash LED controller is present inside some Qualcomm Technologies, Inc. PMICs.
14 The flash LED module can have different number of LED channels supported
15 e.g. 3 or 4. There are some different registers between them but they can
16 both support maximum current up to 1.5 A per channel and they can also support
17 ganging 2 channels together to supply maximum current up to 2 A. The current
18 will be split symmetrically on each channel and they will be enabled and
19 disabled at the same time.
