2019-04-12regulator: dbx500-prcmu: Remove unused fields from struct dbx500_regulator_infoAxel Lin1-5/+5
The *dev is assigned but not used, remove it. Current driver is using devm_regulator_register(), so no neeed to save *rdev for clean up. Use a local variable instead. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@kernel.org>

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2014-03-21regulator: db8500-prcmu: Set 1.8V as a fixed voltage for vsmps2Ulf Hansson1-0/+2

2013-03-01regulator: db8500-prcmu - remove incorrect __exit markupDmitry Torokhov1-2/+2
Even if bus is not hot-pluggable, the devices can be unbound from the driver via sysfs, so we should not be using __exit annotations on remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes.

2012-07-09mfd: Register db8500-prcmu devices using the newly DT:ed MFD APILee Jones1-6/+0
Now the MFD API is Device Tree aware we can use it for platform registration again, even when booting with DT enabled. To aid in Device Node pointer allocation we provide each cell with the associative compatible string.

2012-06-17regulator: Change db8500-prcmu match names to reflect Device TreeLee Jones1-20/+20
The 'name' field in 'struct of_regulator_match' expects to match with its corresponding regulator device node in the Device Tree. This patch renames each of the regulators in the db8500-prcum regulator driver so this is true.

2012-05-18regulator: db8500-prcmu: Separate regulator registration from probeLee Jones1-27/+44
This will provide us with a convenient way to register regulators when booting with Device Tree both enabled & disabled and will save us a great deal of code duplication in time. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-04-09regulator: core: Use a struct to pass in regulator runtime configurationMark Brown1-2/+6
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.

2012-01-20regulators/db8500: split off shared dbx500 codeBengt Jonsson1-86/+32
As we progress with DB5500 and future voltage domain regulators based on very similar hardware as found in the DB8500 PRCMU, it makes sense to split off the generic parts and introduce some generic debug code for the DBx500 regulators. This patch accoplish a basic abstraction of the DBx500 voltage domain regulators.

2011-11-23regulator: pass additional of_node to regulator_register()Rajendra Nayak1-1/+1
With device tree support for regulators, its needed that the regulator_dev->dev device has the right of_node attached. To be able to do this add an additional parameter to the regulator_register() api, wherein the dt-adapted driver can then pass this additional info onto the regulator core.

2011-10-31regulator: Add module.h to drivers/regulator users as requiredPaul Gortmaker1-0/+1
Another group of drivers that are taking advantage of the implicit presence of module.h -- and will break when we pull the carpet out from under them during a cleanup. Fix 'em now. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-24mfd: Move to the new db500 PRCMU APIMattias Nilsson1-1/+1
Now that we have a shared API between the DB8500 and DB5500 PRCMU's, switch to using this neutral API instead. We delete the parts of db8500-prcmu.h that is now PRCMU-neutral, and calls will be diverted to respective driver. Common registers are in dbx500-prcmu-regs.h and common accessors and defines in <linux/mfd/dbx500-prcmu.h> This way we get a a lot more abstraction and code reuse.

2011-05-26regulator: Use device platform_data to retrieve db8500 platform bitsSamuel Ortiz1-2/+2
With the addition of a platform device mfd_cell pointer, MFD drivers can go back to passing platform data back to their sub drivers. This allows for an mfd_cell->mfd_data removal and thus keep the sub drivers MFD agnostic. This is mostly needed for non MFD aware sub drivers.

2011-05-24mach-ux500: voltage domain regulators for DB8500Bengt Jonsson1-0/+558
The DB8500 has ePOD:s (electronic power domains) which are possible to switch on/off to deactivate silicon blocks on the DB8500 SoC by cutting their power without retention. We model these as simple regulators with one bit on/off settings.
