2009-06-15regulator: remove driver_data direct access of struct deviceGreg Kroah-Hartman
In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions.

2009-06-15regulator: Move regulator drivers to subsys_initcall()Mark Brown
Regulators need to be available early in init in order to allow them to be available for consumers when requested. This is generally done by registering them at subsys_initcall() time but not all regulator drivers have done that. Convert these drivers to do so in order to mimimise future support.

2009-03-31regulator: Pass regulator init data as explict argument when registeringMark Brown
Rather than having the regulator init data read from the platform_data member of the struct device that is registered for the regulator make the init data an explict argument passed in when registering. This allows drivers to use the platform data for their own purposes if they wish. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
2009-01-17move wm8400-regulator's probe function to .devinit.textUwe Kleine-König
A pointer to wm8400_regulator_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

2008-10-13regulator: Add WM8400 regulator supportMark Brown
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.
