Use devm_iio_device_register instead of iio_device_register when the remove
function is only used to call iio_device_unregister in order to ease the error path.
Since resource managed functions implicitly call unregister at driver detach also remove
iio_device_unregister

Enhance interrupt generation in the dummy driver and expand its usage
by introducing the irq_work infrastructure to trigger an interrupt.
This way, the irq_work_queue() wrapper permits calling both of the top
half and threaded part from a hard irq context, unlike handle_nested_irq(),
which only calls the threaded part.
As an outcome, the driver succeeds in simulating real hardware
interrupts, while keeping the normal interrupt flow.

The SPI core always reports the MODALIAS uevent as "spi:<modalias>"
regardless of the mechanism that was used to register the device
(i.e: OF or board code) and the table that is used later to match
the driver with the device (i.e: SPI id table or OF match table).
So drivers needs to export the SPI id table and this be built into
the module or udev won't have the necessary information to autoload
the needed driver module when the device is added.

For each buffer type specify the supported device modes for this buffer.
This allows us for devices which support multiple different operating modes
to pick the correct operating mode based on the modes supported by the
attached buffers.
It also prevents that buffers with conflicting modes are attached
to a device at the same time or that a buffer with a non-supported mode is
attached to a device (e.g. in-kernel callback buffer to a device only

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is

Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
appropriate.

This patch refactors the isl29018 driver code in order to use standard
sysfs attributes for scale and integration time.
ISL29018 light sensor uses four ranges and four ADC's resolutions
which influence the calculated lux. Adc resolution is strongly
connected to integration time and range should be controlled by scale.
This patch introduces the usage of integration time and scale instead
of adc resolution and range.

This patch renames lux_scale to calibscale and lux_uscale to
ucalibscale.
This is done in order to avoid confusion since these parameters are
used for hardware applied calibration.

This patch removes non-standard sysfs attributes range, range_available,
adc_resolution and adc_resolution_available. It also removes the
corresponding show and store functions.
This is in preparation for using standard IIO attributes in order to move
the code out of staging.
