From: Stephen Warren <swarren@xxxxxxxxxx>
Seaboard uses a TPS6586x regulator. Instantiate this, and hook up a
couple of fixed GPIO-controlled regulators too.
The regulator configurations were mostly taken from the ChromeOS 3.2
kernel. Exceptions are:
* The schematic lists a fixed voltage for each rail, whereas the ChromeOS
kernel lists a range for many rails. I used the values from the ChromeOS
kernel in all cases, since I know the board file there is the most
complete available for this hardware.
* The vdd_1v2 fixed regulator is present only in the schematic. So, I added
this based on the schematic.
* A 3.3v fixed regulator using GPIO3 of the TPS6586x is present in the
ChromeOS kernel, but not in the schematic. So, I dropped this based on
the schematic.
