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.
