From: Stephen Warren <[email protected]> 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.
