2013-01-03Drivers: iio: remove __dev* attributes.Greg Kroah-Hartman14-69/+69
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-09-17iio:dac: Add ad5755 driverLars-Peter Clausen3-0/+662
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.

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.

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 Clausen2-35/+173
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.

2012-06-05staging:iio: Move DAC drivers out of stagingLars-Peter Clausen15-0/+5239
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.
