This patch adds support for using the TPS65070 PMIC found on the DA850/OMAP-L138 EVM. It defines the power rail consumer mapping and registers the the I2C based PMIC as a board device. The power rail constraints are derived from the maxmimum and minimum recommended operating condition values of the respective consumers derived from section 5.2 of the OMAP-L138 datasheet.
