2009-12-01mfd: Correct WM831X_MAX_ISEL_VALUEMark Brown
There was confusion between the array size and the highest ISEL value possible. Reported-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-09-17regulator: Add WM831x LDO supportMark Brown
The WM831x series of devices provide three types of LDO: - General purpose LDOs supporting voltages from 0.9-3.3V - High performance analogue LDOs supporting voltages from 1-3.5V - Very low power consumption LDOs intended to support always on functionality. This patch adds support for all three kinds of LDO. Each regulator is probed as an individual platform device with resources used to provide the register map location of the regulator. Mixed hardware and software control of regulators is not current supported.

2009-09-17regulator: Add WM831x DC-DC buck convertor supportMark Brown
The WM831x series of devices all have 3 DC-DC buck convertors. This driver implements software control for these regulators via the regulator API. Use with split hardware/software control of individual regulators is not supported, though regulators not controlled by software may be controlled via the hardware control interfaces.

2009-09-17mfd: Export ISEL values from WM831x coreMark Brown
The current settings which can be used with the WM831x current sinks can't easily be mapped between register values and currents at run time without a lookup table since the values scale logarithmically to match the way the human eye interprets brightness. This lookup table is inclided in the core since several drivers need to use it. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
