regulator: Add REGULATOR_STATUS_UNDEFINED.

2012-07-12T17:19:24+00:00

REGULATOR_STATUS_UNDEFINED is to be returned by regulator, if any other state doesn't really apply. Signed-off-by: Krystian Garbaciak Signed-off-by: Mark Brown

regulator: core: Add core support for GPIO controlled enable lines

2012-07-03T19:29:27+00:00

It is very common for regulators to support having their enable signal controlled by a GPIO. Since there are a bunch of fiddly things to get right like handling the operations when the enable signal is tied to a rail and it's just replicated code add support for this to the core. Drivers should set ena_gpio in their config if they have a GPIO control, using ena_gpio_flags to specify any flags (including GPIOF_OUT_INIT_ for the initial state) and ena_gpio_invert if the GPIO is active low. The core will then override any enable and disable operations the driver has and instead control the specified GPIO. This will in the future also allow us to further extend the core by identifying when several enable signals have been tied together and handling this properly. Signed-off-by: Mark Brown

regulator: core: Allow fixed enable_time to be set in the regulator_desc

2012-07-03T19:28:33+00:00

Many regulators have a fixed specification for their enable time. Allow this to be set in the regulator_desc as a number to save them having to implement an explicit operation. Signed-off-by: Mark Brown

regulator: core: Change the unit of ramp_delay from mV/uS to uV/uS

2012-06-18T09:56:58+00:00

This change makes it possible to set ramp_delay with 0.xxx mV/uS without truncation issue. Signed-off-by: Axel Lin Signed-off-by: Mark Brown

regulator: Add ramp_delay configuration to constraints

2012-06-17T20:08:52+00:00

For some hardwares ramp_delay for BUCKs is a configurable parameter which can be configured through DT or board file.This patch adds ramp_delay to regulator constraints and allow user to configure it for regulators which supports this feature, through DT or board file. It will provide two ways of setting the ramp_delay for a regulator: First, by setting it as constraints in board file(for configurable regulators) and set_machine_constraints() will take care of setting it on hardware by calling(the provided) .set_ramp_delay() operation(callback). Second, by setting it as data in regulator_desc(as fixed/default ramp_delay rate) for a regulator in driver. regulator_set_voltage_time_sel() will give preference to constraints->ramp_delay while reading ramp_delay rate for regulator. Similarly users should also take care accordingly while refering ramp_delay rate(in case of implementing their private .set_voltage_time_sel() callbacks for different regulators).

regulator: core: Add regulator_set_voltage_time_sel to calculate ramp delay.

2012-06-11T04:01:46+00:00

This patch adds regulator_set_voltage_time_sel(), to move into core, the commonly used code by drivers to provide the .set_voltage_time_sel callback. It will also allow us to configure different ramp delay for different regulators easily. Signed-off-by: Yadwinder Singh Brar Signed-off-by: Mark Brown

regulator: core: Allow drivers to set voltage mapping table in regulator_desc

2012-06-03T12:19:45+00:00

Some regulator hardware use table based mapping can set volt_table in regulator_desc and use regulator_list_voltage_table() for their list_voltage callback. Signed-off-by: Axel Lin Acked-by: Liam Girdwood Signed-off-by: Mark Brown

regulator: core: Allow drivers to set simple linear voltage maps as data

2012-05-12T10:11:32+00:00

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.

regulator: core: Allow regulators to provide a voltage to selector mapping

2012-05-12T10:11:23+00:00

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.
