| /* |
| * Power Tree |
| * |
| * 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. |
