55 * Power Tree
56 *
57 * In general an attempt is made to include all rails called out by
58 * the schematic as long as those rails interact in some way with
59 * the AP. AKA:
60 * - Rails that only connect to the EC (or devices that the EC talks to)
61 * are not included.
62 * - Rails _are_ included if the rails go to the AP even if the AP
63 * doesn't currently care about them / they are always on. The idea
64 * here is that it makes it easier to map to the schematic or extend
65 * later.
66 *
67 * If two rails are substantially the same from the AP's point of
68 * view, though, we won't create a full fixed regulator. We'll just
69 * put the child rail as an alias of the parent rail. Sometimes rails
70 * look the same to the AP because one of these is true:
71 * - The EC controls the enable and the EC always enables a rail as
72 * long as the AP is running.
73 * - The rails are actually connected to each other by a jumper and
74 * the distinction is just there to add clarity/flexibility to the
75 * schematic.

483 *
484 * When we go into S3 ARM Trusted Firmware will transition our PWM regulators
485 * from wherever they're at back to the "default" operating point (whatever
486 * voltage we get when we set the PWM pins to "input").
487 *
488 * This quick transition under light load has the possibility to trigger the
489 * regulator "over voltage protection" (OVP).
490 *
491 * To make extra certain that we don't hit this OVP at suspend time, we'll
492 * transition to a voltage that's much closer to the default (~1.0 V) so that
493 * there will not be a big jump. Technically we only need to get within 200 mV
494 * of the default voltage, but the speed here should be fast enough and we need
495 * suspend/resume to be rock solid.
