| |
| The AS3645A flash LED controller can drive two LEDs, one high current |
| flash LED and one indicator LED. The high current flash LED can be |
| used in torch mode as well. |
| |
| Ranges below noted as [a, b] are closed ranges between a and b, i.e. a |
| and b are included in the range. |

| Required properties |
| =================== |
| |
| compatible : Must be "ams,as3645a". |
| reg : The I2C address of the device. Typically 0x30. |
