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.
