2016-04-03iio: remove unused gpio consumer.h includeIrina Tirdea
GPIO handling code has been removed from the drivers (since this is now handled by the ACPI core) in commit 0f0796509c07 ("iio: remove gpio interrupt probing from drivers that use a single interrupt"). Remove the include for linux/gpio/consumer.h since it is no longer used. Signed-off-by: Irina Tirdea <irina.tirdea@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2015-11-08iio: Reconcile operation order between iio_register/unregister and pm functionsAdriana Reus
At probe, runtime pm should be setup before registering the sysfs interface so that all the power attributes are accurate and functional when registering. Also, when removing the device we should unregister first to make sure that the interfaces that may result in wakeups are no longer available. Fix this behaviour for the following drivers: bmc150, bmg160, kmx61, kxcj-1013, mma9551, mma9553, rpr0521.

2015-10-03iio: remove gpio interrupt probing from drivers that use a single interruptOctavian Purdila
Commit 845c877009cf014b ("i2c / ACPI: Assign IRQ for devices that have GpioInt automatically") automatically assigns the first ACPI GPIO interrupt in client->irq, so we can remove the probing code from drivers that use only one interrupt.

2015-07-23iio: fix drivers that consider 0 as a valid IRQ in client->irqOctavian Purdila
Since patch "i2c / ACPI: Use 0 to indicate that device does not have interrupt assigned" [1], 0 is not a valid i2c client irq anymore, so change all driver's checks accordingly. The same issue occurs when the device is instantiated via device tree with no IRQ, or from the i2c sysfs interface, even before the patch above.

2015-03-07iio: fix drivers that check buffer->scan_maskOctavian Purdila
If the in-kernel push interface is used we may have a different masks on the device buffer and the kernel buffer and in this case the device should generate data for the reunion of the buffers, which is available at indio_dev->active_scan_mask. Compiled tested only except for bmc150-accel which was tested at runtime with the hardware.

This fixes parts of kmx61 error handling to make code easier to read and to be more consistent with IIO coding conventions: * prefer as single point for error handling instead of duplicating code for each function * directly return a value from a case branch instead of breaking * fix error message for writing REG_CTRL1 Also, add separate error paths for kmx61_trigger_setup/iio_triggered_buffer_setup calls.
