 43      List of child nodes that specify the regulator initialization data.
 44      Child nodes must be named after their hardware counterparts:
 45      buck[1-6], ldoa[1-3], swa1, swb[1-2], and vtt.
 46      Each child node is defined using the standard binding for regulators and
 47      the optional regulator properties defined below.
