  20          * In general an attempt is made to include all rails called out by
  21          * the schematic as long as those rails interact in some way with
  22          * the AP.  AKA:
  23          * - Rails that only connect to the EC (or devices that the EC talks to)
  24          *   are not included.
  25          * - Rails _are_ included if the rails go to the AP even if the AP
  26          *   doesn't currently care about them / they are always on.  The idea
  27          *   here is that it makes it easier to map to the schematic or extend
  28          *   later.
  29          *
  30          * If two rails are substantially the same from the AP's point of
  31          * view, though, we won't create a full fixed regulator.  We'll just
  32          * put the child rail as an alias of the parent rail.  Sometimes rails
  33          * look the same to the AP because one of these is true:
  34          * - The EC controls the enable and the EC always enables a rail as
  35          *   long as the AP is running.
  36          * - The rails are actually connected to each other by a jumper and
  37          *   the distinction is just there to add clarity/flexibility to the
  38          *   schematic.
