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