1 | TPS65217 family of regulators |
| 2 | ||
| 3 | Required properties: | |
| 4 | - compatible: "ti,tps65217" | |
| 5 | - reg: I2C slave address | |
| 6 | - regulators: list of regulators provided by this controller, must be named | |
| 7 | after their hardware counterparts: dcdc[1-3] and ldo[1-4] | |
| 8 | - regulators: This is the list of child nodes that specify the regulator | |
| 9 | initialization data for defined regulators. Not all regulators for the given | |
| 10 | device need to be present. The definition for each of these nodes is defined | |
| 11 | using the standard binding for regulators found at | |
| 12 | Documentation/devicetree/bindings/regulator/regulator.txt. | |

14 | Optional properties: |
| 15 | - ti,pmic-shutdown-controller: Telling the PMIC to shutdown on PWR_EN toggle. | |

17 | The valid names for regulators are: |
| 18 | tps65217: dcdc1, dcdc2, dcdc3, ldo1, ldo2, ldo3 and ldo4 | |
| 19 | ||
| 20 | Each regulator is defined using the standard binding for regulators. | |
| 21 | ||
| 22 | Example: | |
| 23 | ||
| 24 | tps: tps@24 { | |
| 25 | compatible = "ti,tps65217"; | |
| eb433dad | 26 | ti,pmic-shutdown-controller; |
