	 * 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.

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