regulator: Constify constraints name

2011-10-14T19:59:30Z

There's no need for the API to modify it and having it const makes it easier to use with random strings the board code has. Signed-off-by: Mark Brown

regulator: Support voltage offsets to compensate for drops in system

2011-05-27T09:34:37Z

Some systems, particularly physically large systems used for early prototyping, may experience substantial voltage drops between the regulator and the consumers as a result of long traces in the system. With these systems voltages may need to be set higher than requested in order to ensure reliable system operation. Allow systems to work around such hardware issues by allowing constraints to supply an offset to be applied to any requested and reported voltages. This is not ideal, especially since the voltage drop may be load dependant, but is sufficient for most affected systems, it is not expected to be used in production hardware. The offset is applied after all constraint processing so constraints should be specified in terms of consumer values not physically configured values.

regulator: Remove supply_regulator_dev from machine configuration

2011-05-27T09:34:37Z

supply_regulator_dev (using a struct pointer) has been deprecated in favour of supply_regulator (using a regulator name) for quite a few releases now with a warning generated if it is used and there are no current in tree users so just remove the code.

Regulator: add suspend-finish API for regulator core.

2011-03-26T14:15:04Z

The regulator core had suspend-prepare that turns off the regulators when entering a system-wide suspend. However, it did not have suspend-finish that pairs with suspend-prepare and the regulator core has assumed that the regulator devices and their drivers support autonomous recover at resume. This patch adds regulator_suspend_finish that pairs with the previously-existed regulator_suspend_prepare. The function regulator_suspend_finish turns on the regulators that have always_on set or positive use_count so that we can reset the regulator states appropriately at resume. In regulator_suspend_finish, if has_full_constraints, it disables unnecessary regulators.

regulator: Add option for machine drivers to enable the dummy regulator

2010-10-28T21:40:31Z

Allow machine drivers to explicitly enable the use of the dummy regulator, enabling simpler support for systems with only a few specific supplies visible to software. It is strongly recommended that this is not used on systems with substantial software control over their PMICs, for maximum functionality constrints should be as fully specified as possible.

regulator: Allow regulator-regulator supplies to be specified by name

2010-05-25T09:16:01Z

When one regulator supplies another allow the relationship to be specified using names rather than struct regulators, in a similar manner to that allowed for consumer supplies. This allows static configuration at compile time, reducing the need for dynamic init code. Also change the references to LINE supply to be system supply since line is sometimes used for actual supplies and therefore potentially confusing.

regulator: Handle regulators without suspend mode configuration

2009-12-17T10:27:25Z

Since some regulators in the system may not support suspend mode configuration we need to allow some regulators to have a missing suspend mode configuration. Do this by requiring that disabled regulators are explicitly flagged and then skip over regulators that have no state specified. Try to avoid surprises by warning the if we could set the state but no configuration is provided. This also ensures that an all zeros configuration generates a warning rather than silently disabling the regulator. Reported-by: Joonyoung Shim Signed-off-by: Mark Brown Signed-off-by: Liam Girdwood

regulator: Define full constraints function with REGULATOR disabled

This allows machine drivers to build without ifdefs if they have full constraints. Suggested by machine drivers contributed by Haojian Zhuang . Signed-off-by: Mark Brown Signed-off-by: Liam Girdwood
