2012-05-13regulator: tps62360: add dt supportLaxman Dewangan
Add dt support for the pmu device tps62360 and Add binding documentation with example. With this patch driver will support both device-tree and non-device tree registration. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-05-13regulator: tps62360: make init_data of platform data to pointer.Laxman Dewangan
Convert platform data member regulator_init_data to pointer type. This will avoid the copy of entire regualator init data into platform data member when adding dt support and it can be achieve by simple assignment: pdata->init_data = of_get_regulator_init_data(dev, dev->of_node); Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

Only the alive LDOs can actually use this as all the other regulators have two linear ranges. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-05-12regulator: core: Allow drivers to set simple linear voltage maps as dataMark Brown
A lot of regulator hardware maps selectors on to voltages with a simple linear mapping function selector = base + (selector * step size) Provide off the shelf list_voltage() and map_voltage() operations which use new min_uV and uV_step members in the regulator_desc to implement this function.

2012-05-12regulator: core: Allow regulators to provide a voltage to selector mappingMark Brown
In order to allow more drivers to factor things out into data allow drivers to provide a mapping function to convert voltages into selectors. This allows any driver to use set_voltage_sel(). The existing mapping based on iterating over list_voltage() is provided as an operation which can be assigned to the new map_voltage() function though for ease of transition it is treated as the default.

2012-05-10regulator: core: Warn on missing struct deviceMark Brown
The core really wants a struct device to be supplied for regulators and there's no reason this should be impossible so provide one so complain if we didn't get one. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>

2012-05-10regulator: wm831x: Register all normal regulatorsMark Brown
Register all normal regulators rather than skipping unconfigured ones now that the core can handle regulators without init data. Skip the boost and isink regulators since they are normally controlled by other drivers. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-05-09regulator: twl-regulator: make TWL4030_ALLOW_UNSUPPORTED more configurable.NeilBrown
The regulators in the twl4030 can provide some voltage settings that are not offically supported. These settings are disabled by default, but can be enabled with CONFIG_TWL4030_ALLOW_UNSUPPORTED=y However - that config variable is not mentioned in any Kconfig so cannot be used, and - a global setting is clumsy - a per regulator setting would be better. So define a new 'feature' flag that a board file can set to enable these unsupported volatages for boards which need them. This flag cannot (yet) be set using device-tree.

2012-05-08regulator: tps62360: fix stylistic issue and optimize codeLaxman Dewangan
Fix multiple stylistic issue like: - The print message should be not break into multiple line. - line gap after variable declaration and statement. - checkpatch error. - some typo. Some enhancement on error message printing to print error value also along with proper text. Avoid voltage_base conversion to microvolts every time. Put init functions in init section. Using efficient function inplace of calling multiple function to reduce the code size.

2012-05-07regulator: Actually free the regulator in devm_regulator_put()Mark Brown
It turns out that (quite surprisingly) devres_destroy() only undoes the devres mapping, it doesn't destroy the underlying resource, meaning that anything using devm_regulator_put() would leak. While we wait for the new devres_release() which does what we want to get merged open code it in devm_regulator_put().

Looking up init data for regulators found on chips is a common operation that can be handled in a generic way.

2012-04-23regulator: Remove unneeded include of linux/delay.h from regulator driversAxel Lin
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>

max8997_charger_fixedstate_ops If is_enabled callback is not implemented, the core assumes that the regulator is on.
