|

- List of regulators provided by this controller, must be named |

after their hardware counterparts: dcdc[1-6] and ldo1 |

- This is the list of child nodes that specify the regulator |

initialization data for defined regulators. Not all regulators for the given |

device need to be present. The definition for each of these nodes is defined |

using the standard binding for regulators found at ./regulator.txt. |

The valid names for regulators are: |

tps65217: regulator-dcdc1, regulator-dcdc2, regulator-dcdc3, regulator-dcdc4, |

regulator-dcdc5, regulator-dcdc6, regulator-ldo1, regulator-ls3. |
