* regulator: use dev_get_platdata()Jingoo Han2013-07-301-1/+1
| | | | | | | | Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Mark Brown <broonie@linaro.org>
* regulator: max8973: initial DT supportGuennadi Liakhovetski2013-06-241-12/+25
| | | | | | | | | | | | | This patch adds primitive DT support to the max8973 regulator driver. None of the configuration parameters, supported in the platform data are yet available in DT, therefore no configuration is performed if booting with no platform data. This means, that DT instantiation can only be used on boards, where no run-time configuration of the chip is required. In such cases the driver can be used to scale its output voltage. In the future support for configuration parameters should be added. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski+renesas@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>
* regulators: max8973: fix multiple instance supportGuennadi Liakhovetski2013-06-211-5/+7
| | | | | | | | | | | Currently the max8973 regulator driver uses a single static struct of regulator operations for all chip instances, but can overwrite some of its members depending on configuration. This will affect all other MAX8973 instances on the system. This patch fixes this bug by allocating a separate copy of the struct for each chip instance.

* regulator: max8973: Don't override control1 variable when set ramp delay bitsAxel Lin2013-04-241-5/+5
| | | | | | | | | Current code overrides control1 variable when setting ramp delay bits. Fix it by just setting ramp_delay bits. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* Drivers: regulator: remove __dev* attributes.Greg Kroah-Hartman2013-01-031-6/+6
| | | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* regulator: max8973: add regulator driver supportLaxman Dewangan2012-11-191-0/+505
The MAXIM MAX8973 high-efficiency, three phase, DC-DC step-down switching regulator delievers up to 9A of output current. Each phase operates at a 2MHz fixed frequency with a 120 deg shift from the adjacent phase, allowing the use of small magnetic component. Add regulator driver for this device.
