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

2010-10-28T21:40:31+00:00

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

2010-05-25T09:16:01+00:00

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

2009-12-17T10:27:25+00:00

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.

regulator: Define full constraints function with REGULATOR disabled

2009-09-22T12:32:36+00:00

This allows machine drivers to build without ifdefs if they have
full constraints. Suggested by machine drivers contributed by
Haojian Zhuang .

regulator: Allow consumer supplies to be set up with dev_name()

2009-09-22T12:32:36+00:00

Follow the approach suggested by Russell King and implemented by him in
the clkdev API and allow consumer device supply mapings to be set up
using the dev_name() for the consumer instead of the struct device.
In order to avoid making existing machines instabuggy and creating merge
issues the use of struct device is still supported for the time being.

This resolves problems working with buses such as I2C which make the
struct device available late providing that the final device name is
known, which is the case for most embedded systems with fixed setups.

Consumers must still use the struct device when calling regulator_get().

regulator: Support disabling of unused regulators by machines

2009-03-31T08:56:29+00:00

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: Allow boot_on regulators to be disabled by clients

2009-03-31T08:56:27+00:00

Rather than incrementing the reference count for boot_on regulators
(which prevents them being disabled later on) simply force the
regulator to be enabled when applying the constraints. Previously
boot_on was essentially equivalent to always_on.

regulator: Allow regulators to set the initial operating mode

2009-03-31T08:56:24+00:00

This is useful when wishing to run in a fixed operating mode that isn't
the default.
