iio: dac/ad5755: signedness bug in ad5755_setup_pdata()

2012-09-22T09:09:40Z

We need "ret" to be signed for the error handling to work correctly. Signed-off-by: Dan Carpenter Acked-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron

iio:dac: Add ad5755 driver

2012-09-17T19:55:54Z

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.

iio:ad5446: Add device ids for ad5301/ad5311/ad5321

2012-09-08T09:14:46Z

The ad5301/ad5311/ad5321 are software compatible to the ad5602/ad5612/ad5622. Signed-off-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron

iio:ad5446: Add support for the ad5300/ad5310/ad5320

2012-09-08T09:14:45Z

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. Signed-off-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron

iio:ad5446: get rid of private header file

2012-09-03T19:26:45Z

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 Signed-off-by: Jonathan Cameron

iio:ad5446: Add support for I2C based DACs

2012-09-03T19:26:45Z

This patch adds support for I2C based single channel DACs to the ad5446 driver. Specifically AD5602, AD5612 and AD5622. V1: from Lars-Peter Clausen V2: Split the device IDs into two enums and move them to the c file. Signed-off-by: Jean-Francois Dagenais Acked-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron

iio: dac: ad5064: fix section mismatch in ad5064_init() in linux-next

2012-07-12T19:00:08Z

ad5064_init() calls ad5064_spi_unregister_driver() which is annotated __exit. Signed-off-by: Gerard Snitselaar Acked-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron

iio: ad5064: Move bus write callbacks to #if protected sections

2012-07-12T16:57:16Z

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 Signed-off-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron

iio:dac:ad5064: Add support for the ad5629r and ad5669r

2012-06-30T09:15:09Z

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. Signed-off-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron

iio:dac:ad5446: Add support for the AD5450/51/52/53

2012-06-26T21:57:30Z

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. Signed-off-by: Lars-Peter Clausen Acked-by: Jonathan Cameron Signed-off-by: Greg Kroah-Hartman
