| 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. | |
