* regulator: ab3100: Use regulator_map_voltage_iterate()Axel Lin2012-05-18
| | | | | | | | | | | | regulator_map_voltage_iterate() is for drivers implementing set_voltage_sel() and list_voltage() to use it as their map_voltage() operation. In this case, regulator_map_voltage_iterate() happen to be doing the same thing as ab3100_get_best_voltage_index() function. So we can use it to replace ab3100_get_best_voltage_index() function.

* regulator: Remove unneeded include of linux/delay.h from regulator driversAxel Lin2012-04-23
| | | | | | | | | | | | | All the drivers that need delay for the regulator voltage output voltage to stabilize after being enabled or after being set to a new value has been converted to implement enable_time and set_voltage_time_sel callbacks. Then regulator core will take care of the necessary delay. For the drivers that don't need the delay, don't need to include linux/delay.h. This patch removes the unneeded include of linux/delay.h in regulator drivers. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* regulator: core: Use a struct to pass in regulator runtime configurationMark Brown2012-04-09
| | | | | | | | | | | | | | 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.

* regulator: pass additional of_node to regulator_register()Rajendra Nayak2011-11-23
| | | | | | | | | | | 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.

* mfd: Use mfd cell platform_data for ab3100 cells platform bitsSamuel Ortiz2011-05-26
| | | | | | | | | | 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.

* regulator: Report actual configured voltage to set_voltage()Mark Brown2011-01-12
| | | | | | | | | | | Change the interface used by set_voltage() to report the selected value to the regulator core in terms of a selector used by list_voltage(). This allows the regulator core to know the voltage that was chosen without having to do an explict get_voltage(), which would be much more expensive as it will generally access hardware.

* mfd: AB3100 register access change to abx500 APIMattias Wallin2010-05-27
| | | | | | | | | | | | | | | | The interface for the AB3100 is changed to make way for the ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson Analog Baseband chips. The register access functions are moved out to a separate struct abx500_ops. In this way the interface is moved from the implementation and the sub functionality drivers can keep their interface intact when chip infrastructure and communication mechanisms changes. We also define the AB3550 device IDs and the AB3550 platform data struct and convert the catenated 32bit event to an array of 3 x 8bits.

This adds support for the regulators found in the AB3100 Mixed-Signal IC. It further also defines platform data for the ST-Ericsson U300 platform and extends the AB3100 MFD driver so that platform/board data with regulation constraints and an init function can be passed down all the way from the board to the regulators.
