regulator: DA9055 regulator driver
This is the Regulator patch for the DA9055 PMIC and has got dependency on the DA9055 MFD core. This patch support all of the DA9055 regulators. The output voltages are fully programmable through I2C interface only. The platform data with regulation constraints is passed down from the board to the regulator. This patch is functionaly tested on SMDK6410 board. DA9055 Evaluation board was connected to the SMDK6410 board.
