0042 List of child nodes that specify the regulator initialization data.
0043 Child nodes must be named after their hardware counterparts:
0044 buck[1-6], ldoa[1-3], swa1, swb[1-2], and vtt.
0045 Each child node is defined using the standard binding for regulators and
0046 the optional regulator properties defined below.
