18          * Power Tree

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.
