[PATCHv2 1/2] ARM: tegra: tamonten: add the base board regulators

From: Alban Bedel
Date: Thu Jun 19 2014 - 09:26:42 EST


Currently the Tamonten DTS define a fixed regulator for the 5V supply.
However this regulator is in fact on the base board. Fix this by
properly defining the regulators found on the base boards.

v2: * Put the board regualtors in the 'regulator' group with IDs
starting at 100
