* 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.

/* TODO: more properly. Hacky spidev for now???
* A few notes:
* - We either have a Haven here or a Infineon SLB9670. The SLB9670
* is supposed to be a fallback if Haven is broken.
* - Either TPM is supposed to be TPM 2.0 hooked up to SPI. I see some
* kernel support for TPM 2.0 on x86 (hooked up with ACPI) but no
* generic way to say "we have a SPI TPM 2.0". We'll need to add
* a driver for whichever way we go.
* - wfrichar@ says that for Haven if it has gone to sleep we might
* need to add a delay after asserting chip select. Presumably
* haven-specific driver will need to handle this logic (keeping
* track when we last talked and adding an extra delay if it's been
* a while).
