2017-08-22iio:adc: drop assign iio_info.driver_module and iio_trigger_ops.ownerJonathan Cameron1-2/+0
The equivalent of both of these are now done via macro magic when the relevant register calls are made. The actual structure elements will shortly go away. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Lars-Peter Clausen <lars@metafoo.de>

The gpiod API checks for NULL descriptors, so there is no need to duplicate the check in the driver. Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

2016-09-27iio:adc: Add support for AD7766/AD7767Lars-Peter Clausen1-0/+330
Add support for the AD7766, AD7766-1, AD7766-2, AD7767, AD7767-1, AD7767-2 Analog to Digital converters. It's a family of single channel 24-bit SAR ADCs. They are all digital interface compatible and the main difference is the internal decimation rate and analog performance. For communication with the host processor a SPI interface is used. In addition the part has a data ready pin that is pulsed for one MCLK cycle when a conversion has completed and can be used as a IIO trigger.
