2015-10-28spi: Drop owner assignment from spi_driversAndrew F. Davis1-1/+0
An spi_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Andrew F. Davis <afd@ti.com> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Mark Brown <broonie@kernel.org>
2013-12-18iio:dac:ad5755 replaces IIO_ST macro with explicit entries to struct scan_typeJonathan Cameron1-1/+6
IIO_ST is going away as it is a pain to maintain. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Acked-by: Lars-Peter Clausen <lars@metafoo.de>

2013-11-25iio: dac: ad5755: Use devm_iio_device_registerSachin Kamat1-11/+1
devm_iio_device_register simplifies the code. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-10-24iio: dac: ad5755: Remove redundant codeSachin Kamat1-7/+1
The if check is redundant as the value obtained from iio_device_register() is already in the required format. Error messages are already printed by iio_device_register(); hence not needed. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-10-01iio:ad5755: Report scale as fractional valueLars-Peter Clausen1-12/+5
Move the complexity of calculating the fixed point scale to the core. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-09-15iio: refactor info mask and ext_info attribute creation.Jonathan Cameron1-0/+1
Introduce an enum to specify whether the attribute is separate or shared. Factor out the bitmap handling for loop into a separate function. Tidy up error handling and add a NULL assignment to squish a false positive warning from GCC. Change ext_info shared type from boolean to enum and update in all drivers.

2013-08-19iio: dac: ad5755: Use devm_iio_device_allocSachin Kamat1-10/+4
Using devm_iio_device_alloc makes code simpler. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-03-17iio:dac:ad5755 move to info_mask_(shared_by_type/separate)Jonathan Cameron1-5/+5
The original info_mask is going away in favour of the broken out versions. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Acked-by: Lars-Peter Clausen <lars@metafoo.de>
2013-02-09iio: Use spi_sync_transfer()Lars-Peter Clausen1-6/+1
Use the new spi_sync_transfer() helper function instead of open-coding it. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-01-04Drivers: iio: remove __dev* attributes.Greg Kroah-Hartman1-8/+8
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.

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 Clausen1-0/+650
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.
