2012-11-15mfd: tps6586x: move regulator dt parsing to regulator driverLaxman Dewangan
Moving regulator node parsing to regulator driver in place of parsing it on mfd driver. The motivation for this change are: - MFD core driver should not depends on regulator and able to instantiate device without regulator. - The API for matching regulators are in regulator core and it is good that regulator driver only calls this API. - Regulator specific support should be in regulator driver only to ease any enhancement/modification for regulators. - The regulator driver is now registered as mfd sub device and all regulator registration is done from single probe call.

2012-04-09regulator: core: Use a struct to pass in regulator runtime configurationMark Brown
Rather than adding new arguments to regulator_register() every time we want to add a new bit of dynamic information at runtime change the function to take these via a struct. By doing this we avoid needing to do further changes like the recent addition of device tree support which required each regulator driver to be updated to take an additional parameter. The regulator_desc which should (mostly) be static data is still passed separately as most drivers are able to configure this statically at build time.
