iio: dac: mcp4725: set iio name property in sysfs

2016-02-25T19:58:54+00:00

commit 97a249e98a72d6b79fb7350a8dd56b147e9d5bdb upstream. Without this change, the name entity for mcp4725 is missing in /sys/bus/iio/devices/iio\:device*/name With this change, name is reported correctly Signed-off-by: Yong Li Signed-off-by: Jonathan Cameron Signed-off-by: Greg Kroah-Hartman

iio: ad5064: Fix ad5629/ad5669 shift

2016-02-25T19:58:53+00:00

commit 5dcbe97bedd6ba4b0f574a96cc2e293d26f3d857 upstream. The ad5629/ad5669 are the I2C variant of the ad5628/ad5668, which has a SPI interface. They are mostly identical with the exception that the shift factor is different. Currently the driver does not take care of this difference which leads to incorrect DAC output values. Fix this by introducing a custom channel spec for the ad5629/ad5669 with the correct shift factor.

iio:ad5064: Make sure ad5064_i2c_write() returns 0 on success

2016-02-25T19:58:53+00:00

commit 03fe472ef33b7f31fbd11d300dbb3fdab9c00fd4 upstream. i2c_master_send() returns the number of bytes transferred on success while the ad5064 driver expects that the write() callback returns 0 on success. Fix that by translating any non negative return value of i2c_master_send() to 0.

iio: DAC: ad5624r_spi: fix bit shift of output data value

2015-08-03T16:29:53+00:00

commit adfa969850ae93beca57f7527f0e4dc10cbe1309 upstream. The value sent on the SPI bus is shifted by an erroneous number of bits. The shift value was already computed in the iio_chan_spec structure and hence subtracting this argument to 16 yields an erroneous data position in the SPI stream.

iio: ad5686: fix optional reference voltage declaration

2015-03-18T12:31:26+00:00

commit da019f59cb16570e78feaf10380ac65a3a06861e upstream. When not using the "_optional" function, a dummy regulator is returned and the driver fails to initialize. Signed-off-by: Urs Fässler Acked-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron Signed-off-by: Greg Kroah-Hartman

iio:dac:mcp4725 drop specification of scan type as unused in this driver.

2013-12-17T21:08:19+00:00

IIO_ST is going away as it is a pain to maintain so the simplest path with this driver is to not specify the unused scan type. Signed-off-by: Jonathan Cameron Acked-by: Lars-Peter Clausen
