| 2 | |
| 3 | Required Properties: |
| 4 | |
| 5 | - compatible: Must contain "adi,adp1653" |
| 6 | |
| 7 | - reg: I2C slave address |
| 8 | |
| 9 | - enable-gpios: Specifier of the GPIO connected to EN pin |
| 10 | |
| 11 | There are two LED outputs available - flash and indicator. One LED is |
| 12 | represented by one child node, nodes need to be named "flash" and "indicator". |
