   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.
