* iio:adc: drop assign iio_info.driver_module and iio_trigger_ops.ownerJonathan Cameron2017-08-221-1/+0Star
| | | | | | | | | 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>
* iio: adc: add missing of_node references to iio_devMatt Ranostay2016-07-031-0/+1
| | | | | | | | Adding missing indio_dev->dev.of_node references to allow iio consumers to access the device channels. Signed-off-by: Matt Ranostay <mranostay@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* iio:core: timestamping clock selection supportGregor Boirie2016-06-301-1/+2
| | | | | | | | | | | | | | | 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.

* ti-adc081c: Initial triggered buffer supportCrestez Dan Leonard2016-04-171-13/+64
| | | | | | | | | | | Using this requires software triggers like CONFIG_IIO_HRTIMER_TRIGGER. The device can be configured to do internal periodic sampling but does not offer some sort of interrupt on data ready. Interrupts can only trigger when values get out of a specific range.
