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