* regulator: Voltage count for AB3100Linus Walleij2009-09-171-0/+6
| | | | | | | | | This sets the number of voltages for the AB3100 regulators so that they play well with the voltage listing functions and can be used properly with the MMC regulator integration glue for example.

* regulator: AB3100 supportLinus Walleij2009-09-173-0/+704
| | | | | | | | | | | | | | | | 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.

This patch adds support for all three kinds of LDO. Each regulator is probed as an individual platform device with resources used to provide the register map location of the regulator.

* regulator: Support disabling of unused regulators by machinesMark Brown2009-03-311-0/+92
| | | | | | | | | | | | | | | | At present it is not possible for machine constraints to disable regulators which have been left on when the system starts, for example as a result of fixed default configurations in hardware. This means that power may be wasted by these regulators if they are not in use. Provide intial support for this with a late_initcall which will disable any unused regulators if the machine has enabled this feature by calling regulator_has_full_constraints(). If this has not been called then print a warning to encourage users to fully specify their constraints so that we can change this to be the default behaviour in future.

* regulator: Don't increment use_count for boot_on regulatorsMark Brown2009-03-311-1/+0
| | | | | | | | | | | | | | | | | | | | | | Don't set use_count for regulators that are enabled at boot since this stops the supply being disabled by well-behaved consumers which do balanced enables and disabled. Any consumers which don't do disables which are not matched by enables are unable to share regulators - shared regulators are the common case so the API should facilitate them. Consumers that want to disable regulators that are enabled when they start have two options: - Do a regulator_enable() prior to the disable to bring the use count in sync with the hardware state; this will ensure that if the regulator was enabled by another driver then this consumer will play nicely with it. - Use regulator_force_disable(); this explicitly bypasses any checks done by the core and documents the inability of the driver to share the supply.

| | | | | | | | | | | | | | | | | | | | | | | Fix some refcounting issues in the regulator framework, supporting regulator_disable() for regulators that were enabled at boot time via machine constraints: - Update those regulators' usecounts after enabling, so they can cleanly be disabled at that level. - Remove the problematic per-consumer usecount, so there's only one level of enable/disable. Buggy consumers could notice different bug symptoms. The main example would be refcounting bugs; also, any (out-of-tree) users of the experimental regulator_set_optimum_mode() stuff which don't call it when they're done using a regulator.

| | | | | | | | | | | | | | | | | | | | | | | | | | Support most of the LDO regulators in the twl4030 family chips. In the case of LDOs supporting MMC/SD, the voltage controls are used; but in most other cases, the regulator framework is only used to enable/disable a supplies, conserving power when a given voltage rail is not needed. The drivers/mfd/twl4030-core.c code already sets up the various regulators according to board-specific configuration, and knows that some chips don't provide the full set of voltage rails. The omitted regulators are intended to be under hardware control, such as during the hardware-mediated system powerup, powerdown, and suspend states. Unless/until software hooks are known to be safe, they won't be exported here. These regulators implement the new get_status() operation, but can't realistically implement get_mode(); the status output is effectively the result of a vote, with the relevant hardware inputs not exposed.

Use those methods to force machine-level constraints into bounds. (Example: regulator supports 1.8V, 2.4V, 2.6V, 3.3V, and board constraints for that rail are 2.0V to 3.6V ... so the range of voltages is then 2.4V to 3.3V on this board.)
