Jonathan Cameron e64e7d5c8c iio:trigger:sysfs Move out of staging.
This simple driver is rather useful. No issues about its interface
have been raised for some time hence the proposal to move it out
of staging.

Lars-Peter Clausen ec04cb048d staging:iio: Move adis library out of staging
Now that the adis library no longer depends on the sw_ring buffer implementation
we can move it out of staging.

While we are at it also sort the entries in the iio Kconfig and Makefile to be
in alphabetical order.

Jonathan Cameron 92d1079b28 staging:iio: add a callback buffer for in kernel push interface
This callback buffer is meant to be opaque to users, but basically
adds a very simple pass through buffer to which data may be
pushed when it is inserted into the buffer list.

This patch contains the common code, which is used by all HID sensors.
There are some common set of attributes, which every hid sensor
needs it. This patch contains all such attributes processing.
Also the trigger interface is common among all HID sensors. This
patch contains common trigger functions utilized by all HID sensors.

Lars-Peter Clausen 23f2d735a9 iio: Add helper function for initializing triggered buffers
Add a helper function for executing the common tasks which are usually involved
in setting up a simple software ringbuffer. It will allocate the buffer,
allocate the pollfunc and register the buffer.

Lars-Peter Clausen dbdc025bb2 staging:iio: Move DAC drivers out of staging
The IIO DAC drivers are in a reasonably good shape. They all make use of channel
spec and non of them provides non-documented sysfs attributes. Code style should
be OK as well, both checkpatch and coccicheck only report trivial issues.

So lets move the whole folder out of staging.

Michael Hennerich cd1678f963 iio: frequency: New driver for AD9523 SPI Low Jitter Clock Generator
Changes since V1:

Apply Jonathan's review feedback:
Revise device status attribute names, and split documentation into two sections.
Add additional comments, and fix indention issues.
Remove pointless zero initializations.
Revise return value handling.
Simplify some code sections.
Split store_eeprom and sync handling into separate functions.
Use strtobool where applicable.
Document platform data structures using kernel-doc style.

Use dev_to_iio_dev
write_raw IIO_CHAN_INFO_FREQUENCY: Reject values <= 0
Make patch target drivers/iio

Changes since V2:

Use for_each_clear_bit() and __set_bit() where applicable.
Add descriptive comment.
Avoid temporary for struct regulator.
spi_device_id name use ad9523-1, ad9523 will be added later.

Johan Hovold 9c8ea1b29b iio: add LM3533 ambient-light-sensor driver
Add sub-driver for the ambient-light-sensor interface on National
Semiconductor / TI LM3533 lighting power chips.

The sensor interface can be used to control the LEDs and backlights of
the chip through defining five light zones and three sets of
corresponding output-current values.

The driver provides raw and mean adc readings along with the current
light zone through sysfs. A threshold event can be generated on zone
changes. The ALS-control output values can be set per zone for the three
current output channels.

Take the core support + the kfifo buffer implentation out of
staging.  Whilst we are far from done in improving this subsystem
it is now at a stage where the userspae interfaces (provided by
the core) can be considered stable.

Drivers will follow over a longer time scale.
