Lars-Peter Clausen c499d029d8 iio:dac: Add ad5755 driver
This patch adds support for the AD5755, AD5755-1, AD5757, AD5735, AD5737 16 and
14 bit quad-channel DACs. The AD5757/AD5737 only have current outputs, but
for the AD5755/AD5757 each of the outputs can be configured to either be a
voltage or a current output. We only allow to configure this at device probe
time since usually this needs to match the external circuitry and should not be
changed on the fly.

A few trivial formatting changes on merge.

Lars-Peter Clausen bf83238019 iio:ad5446: Add device ids for ad5301/ad5311/ad5321
The ad5301/ad5311/ad5321 are software compatible to the ad5602/ad5612/ad5622.

Lars-Peter Clausen 2fafbce250 iio:ad5446: Add support for the ad5300/ad5310/ad5320
The ad5300/ad5310/ad5320 is a family of single channel DACs with a SPI interface
similar to the ad5601/ad5611/ad5621 but use a different shift factor for the
data word.

While we are at it also reorder the device part numbers in the ad5446 driver
Kconfig to be ordered alphabetically.

Jean-Francois Dagenais 3ec36a2cf0 iio:ad5446: Add support for I2C based DACs
This patch adds support for I2C based single channel DACs to the ad5446
driver. Specifically AD5602, AD5612 and AD5622.

V1: from Lars-Peter Clausen <lars@metafoo.de>
V2: Split the device IDs into two enums and move them to the c file.

Lars-Peter Clausen 6a17a0768f iio:dac:ad5064: Add support for the ad5629r and ad5669r
The ad5629r and ad5669r are the I2C variants of the ad5628 and ad5668. Since the
ad5064 driver currently only supports SPI based devices the major part of this
patch focuses on adding support for I2C based devices. Adding support for the
actual parts boils down to adding entries for them to the device id table.

Lars-Peter Clausen 779c0c4619 iio:dac:ad5446: Add support for the AD5450/51/52/53
This patch adds support for the Analog Devices AD5450/51/52/53 Digital-to-Analog
converters.

The AD5452 and AD5453 are software compatible to the existing AD5444 and AD5446.
The AD5450 and AD5451 are similar but have a smaller resolution.

Peter Meerwald cf35ad61ac iio: add mcp4725 I2C DAC driver
v5:
* fix warnings (Jonathan Cameron)

v4:
* remove unused indio_dev pointer in mcp4725_data (Jonathan Cameron)
* use u16 instead of unsigned short in mcp4725_data (Jonathan Cameron)
* #include mcp4725.h from linux/iio/dac/

v3:
* move from staging to drivers/iio
* switch to chan_spec
* dev_get_drvdata() -> dev_to_iio_dev()
* annotate probe() and remove() with __devinit and __devexit

v2 (based on comments from Jonathan Cameron and Lars-Peter Clausen):
* did NOT switch to chan_spec yet
* rebase to staging-next tree, update iio header locations
* dropped dac.h #include, not needed
* strict_strtol() -> kstrtol()
* call iio_device_unregister() in remove()
* everything in one patch

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.
