Mark Brown 42fad570b6 regulator: Add WM8400 regulator support
The WM8400 provides two programmable DCDC step-down (buck) convertors
and four low-dropout (LDO) regulators. This driver provides support for
runtime managment of these in the standard regulator API.

Support for configuration of the suspend and hibernate mode behaviour
of the regulators is not yet included.

Mark Brown 1d9f9f0400 mfd: Core support for the WM8400 AudioPlus HiFi CODEC and PMU
The WM8400 is a highly integrated audio CODEC and power management unit
optimised for use in mobile multimedia applications.  This patch adds
core support for the WM8400 to the MFD subsystem.

Both I2C and SPI access are supported by the hardware but currently only
I2C access is implemented.  The code is structured to allow SPI support
to be slotted in later.
