2019-05-03regulator: da9xxx: Switch to SPDX identifierAxel Lin1-15/+5
Convert Dialog Semiconductor DA9xxx regulator drivers to SPDX identifier. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2019-03-13regulator: da9211: Fix notifier mutex lock warningSteve Twiss1-0/+4
The mutex for the regulator_dev must be controlled by the caller of the regulator_notifier_call_chain(), as described in the comment for that function. Failure to mutex lock and unlock surrounding the notifier call results in a kernel WARN_ON_ONCE() which will dump a backtrace for the regulator_notifier_call_chain() when that function call is first made. The mutex can be controlled using the regulator_lock/unlock() API.

2018-12-11regulator: da9211: Hand over GPIO to regulator coreLinus Walleij1-0/+6
The GPIO descriptors used by the DA9211 driver are retrieved during probe() and it is really helpful to have those under devres management because of all the errorpaths in the intialization. Using the new dev_gpiod_unhinge() call we can remove the devres management of the descriptor right before handing it over to the regulators core.

2018-10-15regulator: Fetch enable gpiods nonexclusiveLinus Walleij1-5/+5
Since the core regulator code is treating GPIO descriptors as nonexclusive, i.e. it assumes that the enable GPIO line may be shared with several regulators, let's add the flag introduced for fixing this problem on fixed regulators to all drivers fetching GPIO descriptors to avoid possible regressions.
