regulator: provide consumer interface for fall/rise time

2011-03-26T14:15:06+00:00

This exposes the functionality for rise/fall fime when setting
voltage to the consumers.

regulator: add set_voltage_time_sel infrastructure

2011-03-26T14:15:06+00:00

This makes it possible to set the stabilization time for voltage
regulators in the same manner as enable_time(). The interface
only supports regulators that implements fixed selectors.

Regulator: add suspend-finish API for regulator core.

2011-03-26T14:15:04+00:00

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: If we fail when setting up a supply say which supply

2011-03-26T14:15:03+00:00

Makes it a bit easier to identify if it's a problem with the supplies,
the usual error would be omitting the supply name entirely.

regulator: Add initial per-regulator debugfs support

2011-01-12T14:33:05+00:00

We only expose the use and open counts to userspace, providing a tiny
bit of insight into what the API is up to.

regulator: Make regulator_has_full_constraints a bool

2011-01-12T14:33:05+00:00

It's a boolean value so use the type.

regulator: Clean up logging a bit

2011-01-12T14:33:05+00:00

The recent introduction of standard regulator API logging macros means
that all our log messages have at least the function name in them and
logging that the constraints are for the regulator API is probably a
bit much.

regulator: Optimise out noop voltage changes

2011-01-12T14:33:05+00:00

If a consumer sets the same voltage range as is currently configured
for that consumer there's no need to run through setting the voltage
again. This pattern may occur with some CPUfreq implementations where
the same voltage range is used for multiple frequencies.

regulator: Add API to re-apply voltage to hardware

2011-01-12T14:33:05+00:00

When cooperating with an external control source the regulator setup
may be changed underneath the API. Currently consumers can just redo
the regulator_set_voltage() to restore a previously set configuration
but provide an explicit API for doing this as optimsations in the
regulator_set_voltage() implementation will shortly prevent that.
