Subject: [RFC V1] COMMIT 1: DA9210 driver files

From: Steve Twiss <stwiss.opensource@...semi.com>

This is the regulator driver for the Dialog DA9210 Multi-phase Buck.
The patch is relative to linux-next next-20130620

The regulator implements the functions for .enable, .set_voltage,
.get_voltage, .set_current_limit, and .get_current_limit. It uses the
kernel standard functions for .disable, .is_enabled and .list_voltage.

This file contains a regulator driver and I2C driver combined into the
same file and has been tested on a Samsung SMDK6410 connected to a Dialog
DA9210 Evaluation Board through a I2C connection.

It would be appreciated if you could add any comments you may have about
the driver.
