* regulator: core: optimize devm_regulator_bulk_get()Dmitry Torokhov2017-02-041-20/+25
| | | | | | | | | When performing this bulk operation, there is no need to track every supply individually. It is more efficient to treat entire group as a single managed resource. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* regulator: core: have _regulator_get() accept get_type argumentDmitry Torokhov2017-02-041-20/+1
| | | | | | | | | Instead of separate "exclusive" and "allow_dummy" arguments, that formed 3 valid combinations (normal, exclusive and optional) and an invalid one, let's accept explicit "get_type", like we did in devm-managed code.

* regulator: Remove support for optional supplies in the bulk APIBjorn Andersson2016-08-161-5/+2
| | | | | | | | | | The patch was based on my missinterpretation of the API and only accidentally worked for me. Let's clean it out to not confuse others. This reverts commit 3ff3f518a135fa4592fe2817e9ac2cce1fa23dc2. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> Signed-off-by: Mark Brown <broonie@kernel.org>
* regulator: Make bulk API support optional suppliesBjorn Andersson2015-11-171-2/+5
| | | | | | | | Make it possible to use the bulk API with optional supplies, by allowing the consumer to marking supplies as optional in the regulator_bulk_data. Signed-off-by: Bjorn Andersson <bjorn.andersson@sonymobile.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* regulator: core: Add devres versions of notifier registrationCharles Keepax2015-03-051-0/+85
| | | | | | | | | | Add devm_regulator_register_notifier, this adds the resource against the device for the consumer supply we are registering the notifier for. There seem to be few use-cases where this wouldn't be the users intention and this ensures the notifiers will always be removed at the correct time.

* regulator: core: Add ability to create a lookup alias for supplyCharles Keepax2013-10-181-0/+163
| | | | | | | | | | | | | | These patches add the ability to create an alternative device on which a lookup for a certain supply should be conducted. A common use-case for this would be devices that are logically represented as a collection of drivers within Linux but are are presented as a single device from device tree. It this case it is necessary for each sub device to locate their supply data on the main device.

* regulator: core: Split devres code out into a separate fileMark Brown2013-09-171-0/+252
Cut down on the size of core.c a bit more and ensure that the devres versions of things don't do too much peering inside the internals of the APIs they wrap. Signed-off-by: Mark Brown <broonie@linaro.org>
