24 * Power Tree
25 *
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.
