2012-10-25drivers/iio/dac: remove CONFIG_EXPERIMENTALKees Cook
This config item has not carried much meaning for a while now and is almost always enabled by default. As agreed during the Linux kernel summit, remove it.

2012-10-19iio:dac: Add support for the ad5449Lars-Peter Clausen
This patch adds support for the AD5415, AD5426, AD5429, AD5432, AD5439, AD5443 and AD5449 single and dual channel DACs. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

We need "ret" to be signed for the error handling to work correctly. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Acked-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2012-09-17iio:dac: Add ad5755 driverLars-Peter Clausen
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.

2012-09-08iio:ad5446: Add device ids for ad5301/ad5311/ad5321Lars-Peter Clausen
The ad5301/ad5311/ad5321 are software compatible to the ad5602/ad5612/ad5622. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2012-09-08iio:ad5446: Add support for the ad5300/ad5310/ad5320Lars-Peter Clausen
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.

2012-09-03iio:ad5446: get rid of private header fileJean-Francois Dagenais
Most of the defines in there were not even used, and the structs left are private to the .c file. Makes the driver more in line with most of the kernel drivers. Signed-off-by: Jean-Francois Dagenais <jeff.dagenais@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2012-09-03iio:ad5446: Add support for I2C based DACsJean-Francois Dagenais
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.

2012-07-12iio: dac: ad5064: fix section mismatch in ad5064_init() in linux-nextGerard Snitselaar
ad5064_init() calls ad5064_spi_unregister_driver() which is annotated __exit. Signed-off-by: Gerard Snitselaar <dev@snitselaar.org> Acked-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2012-07-12iio: ad5064: Move bus write callbacks to #if protected sectionsLars-Peter Clausen
Move the SPI and I2C specific write callbacks to the respective "#if IS_ENABLED(CONFIG_SPI_MASTER)" and "#if IS_ENABLED(CONFIG_I2C)" protected sections of the code. This fixes the following warning which occurs if CONFIG_I2C is not set: drivers/iio/dac/ad5064.c: In function ‘ad5064_i2c_write’: drivers/iio/dac/ad5064.c:132: error: implicit declaration of function ‘i2c_master_send’ And the follwing warning which occurs when CONFIG_SPI_MASTER is not set: drivers/iio/dac/ad5064.c:137: warning: ‘ad5064_spi_write’ defined but not used Reported-by: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2012-06-30iio:dac:ad5064: Add support for the ad5629r and ad5669rLars-Peter Clausen
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.

2012-06-26iio:dac:ad5446: Add support for the AD5450/51/52/53Lars-Peter Clausen
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.

2012-06-05staging:iio: Move DAC drivers out of stagingLars-Peter Clausen
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.
