/*

|
* 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.
