2017-08-22iio:adc: drop assign iio_info.driver_module and iio_trigger_ops.ownerJonathan Cameron1-1/+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>

2016-06-30iio:core: timestamping clock selection supportGregor Boirie1-1/+1
Adds a new per-device sysfs attribute "current_timestamp_clock" to allow userspace to select a particular POSIX clock for buffered samples and events timestamping. Following clocks, as listed in clock_gettime(2), are supported: CLOCK_REALTIME, CLOCK_MONOTONIC, CLOCK_MONOTONIC_RAW, CLOCK_REALTIME_COARSE, CLOCK_MONOTONIC_COARSE, CLOCK_BOOTTIME and CLOCK_TAI.

2013-01-03Drivers: iio: remove __dev* attributes.Greg Kroah-Hartman1-3/+3
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.

2012-11-10staging:iio: Add support for multiple buffersJonathan Cameron1-1/+1
Route all buffer writes through the demux. Addition or removal of a buffer results in tear down and setup of all the buffers for a given device. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Tested-by: srinivas pandruvada <srinivas.pandruvada@intel.com>
2012-09-17iio: ad7476: Add support for the ad7091rLars-Peter Clausen1-4/+26
Add support for the ad7091r 12 bit ADC to the ad7476 driver. Although the ad7091r is not really related to any of the other devices supported by this driver, luckily for us there are not so many ways (which are not totally insane) how sampling a single channel ADC via SPI can be implemented and support for the ad7091r can be added to the driver with just a few adjustments. The ad7091r requires an external "conversion start" pulse to start a sample conversion. After the conversion has finished the result can be read via SPI. We depend on a IIO trigger to generate this signal, as a result only sampling in buffered mode and not in manual mode is available.

2012-09-15iio:ad7476: Add support for ad7273/ad7274/ad7276/ad7277/ad7278Lars-Peter Clausen1-0/+20
The ad7276/ad7277/ad7278 are similar to the ad7476/ad7477/ad7478 but have the same number of leading zeros as the ad7940. The ad7273/ad7274 have a extra pin for VREF where as for the ad7276/ad7277/ad7278 VREF is taken from VDD, but otherwise they are compatible to the ad7276/ad7277.

2012-09-15iio:ad7476: Add ad7940 supportLars-Peter Clausen1-4/+14
The AD7940 is a single channel 14 bit ADC similar to the ADCs already supported by the ad7476 driver, but it does have a different shift factor. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2012-09-15iio: Move ad7476 driver out of stagingLars-Peter Clausen1-0/+278
The ad7476 driver is a driver for simple single channel ADCs. The driver does not export any experimental or custom ABI files nor do the static code check tools report any issues, so move the driver out of staging.
