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