2020-01-13regulator: Convert i2c drivers to use .probe_newAxel Lin1-3/+2
Use the new .probe_new for i2c drivers. These drivers do not use const struct i2c_device_id * argument, so convert them to utilise the simplified i2c driver registration.

2019-10-07regulator: da9211: switch to using devm_fwnode_gpiod_getDmitry Torokhov1-6/+6
devm_gpiod_get_from_of_node() is being retired in favor of devm_fwnode_gpiod_get_index(), that behaves similar to devm_gpiod_get_index(), but can work with arbitrary firmware node. It will also be able to support secondary software nodes. Let's switch this driver over.

2019-09-11regulator: da9211: fix obtaining "enable" GPIODmitry Torokhov1-1/+1
This fixes 11da04af0d3b, as devm_gpiod_get_from_of_node() does not do translation "con-id" -> "con-id-gpios" that our bindings expects, and therefore it was wrong to change connection ID to be simply "enable" when moving to using devm_gpiod_get_from_of_node().

2019-06-25gpio: Fix return value mismatch of function gpiod_get_from_of_node()Waibel Georg1-0/+2
In case the requested gpio property is not found in the device tree, some callers of gpiod_get_from_of_node() expect a return value of NULL, others expect -ENOENT. In particular devm_fwnode_get_index_gpiod_from_child() expects -ENOENT. Currently it gets a NULL, which breaks the loop that tries all gpio_suffixes. The result is that a gpio property is not found, even though it is there. This patch changes gpiod_get_from_of_node() to return -ENOENT instead of NULL when the requested gpio property is not found in the device tree. Additionally it modifies all calling functions to properly evaluate the return value. Another approach would be to leave the return value of gpiod_get_from_of_node() as is and fix the bug in devm_fwnode_get_index_gpiod_from_child(). Other callers would still need to be reworked. The effort would be the same as with the chosen solution.

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.
