      The first cell is the pin number and the second cell is used to specify

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