regulator: Fix argument format type errors in error prints

2011-07-22T10:46:57+00:00

We need to dereference the pointers to print their values.

regulator: Fix memory leak in set_machine_constraints() error paths

2011-07-22T10:43:59+00:00

Properly kfree rdev->constraints in all set_machine_constraints() error paths.
Also properly kfree rdev->constraints in regulator_register() error paths.

regulator: Make core more chatty about some errors

2011-07-22T10:43:00+00:00

Prevent some head scratching by making the core log about some rare but
possible errors with invalid voltage ranges and modes being set.

regulator: Add basic per consumer debugfs

2011-07-04T16:09:28+00:00

Report the requested load and voltage for each consumer in debugfs when it
is enabled.

regulator: Add rdev_crit() macro

2011-06-09T18:14:35+00:00

No actual users but provide the macro so there's less surprise when it's
not there.

regulator: Refactor supply implementation to work as regular consumers

2011-06-09T18:14:34+00:00

Currently the regulator supply implementation is somewhat complex and
fragile as it doesn't look like standard consumers but is instead a
parallel implementation. This causes issues with locking and reference
counting.

Move the implementation over to using standard consumers to address this.
Rather than only notifying the supply on the first enable/disable we do so
every time the regulator is enabled or disabled, simplifying locking as we
don't need to hold a lock on the consumer we are about to enable.

regulator: Include the device name in the microamps_requested_ file

2011-06-09T18:14:29+00:00

We may have multiple devices requesting a supply with the same name so
include the device name in the generated filename for microamps_requested
to avoid duplicate files.

regulator: Increase the limit on sysfs file names

2011-06-09T18:14:29+00:00

With verbose filenames we can easily hit 32 characters.

regulator: Do bulk enables of regulators in parallel

2011-05-30T10:56:57+00:00

In order to reduce the impact of ramp times rather than enabling the
regulators for a device in series use async tasks to run the actual
enables. This means that the delays which the enables implement can all
run in parallel, though it does mean that the order in which the
supplies come on may be unstable.

For super bonus fun points if any of the regulators are shared between
multiple supplies on the same device (as is rather likely) then this
will test our locking.  Note that in this case we only delay once for
each physical regulator so the threads shouldn't block each other while
delaying.

It'd be even nicer if we could coalesce writes to a shared enable registers
in PMICs but that's definitely future work, and it may also be useful
and is certainly more achievable to optimise out the parallelism if none
of the regulators implement ramp delays.

regulator: Fix _regulator_get_voltage if get_voltage callback is NULL

2011-05-27T09:49:30+00:00

In the case of get_voltage callback is NULL, current implementation in
_regulator_get_voltage will return -EINVAL.

Also returns proper error if ret is negative value.
