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: initialization for ab8500 regulators

2011-03-26T14:15:05+00:00

The regulators on the AB8500 have a lot of custom
hardware control settings pertaining to 8 external
signals, settings which are board-specific and need
be provided from the platform at startup.

Initialization added for regulators Vana, VextSupply1,
VextSupply2, VextSupply3, Vaux1, Vaux2, Vaux3, VTVout,
Vintcore12, Vaudio, Vdmic, Vamic1, Vamic2, VrefDDR.

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: 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: 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.

regulator: Provide a selector based set_voltage_sel() operation

2011-01-12T14:33:04+00:00

Many regulator drivers implement voltage setting by looping through a
table of possible values, normally because the set of available voltages
can't be mapped onto selectors with simple calcuation. Factor out these
loops by providing a variant of set_voltage() which takes a selector rather
than a voltage range as an argument and implementing a loop through the
available selectors in the core.

This is not going to be suitable for use with all devices as when the
regulator voltage can be mapped onto selector values with a simple
calculation the linear scan through the available values will be more
expensive than just doing the calculation, especially for regulators
that provide fine grained voltage control.

regulators: Moved define for number of regulators in ab8500

2011-01-12T14:33:02+00:00

The define for number of regulators is moved from ab8500-core to
ab8500-regulator so that the regulator driver can be updated
independently of ab8500-core. This also changes the platform
configuration structure of ab8500-core so that it contains a
pointer to the regulator_init_data array plus number of
regulators instead of an fixed size array of pointers to
regulator_init_data.

regulator: Allow drivers to report voltages as selectors

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

Since drivers already have to provide an API for translating selectors
into voltages they may as well just report the selector values directly
to the core API rather than implement the lookup themselves. The old
interface is left in place for now, but may be removed in future.
