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