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.

2013-03-17iio:adc:ad7923: Add support for the ad7904/ad7914/ad7924Lars-Peter Clausen1-13/+50
The ad7924 is software compatible with the ad7923. The ad7904 and ad7914 are the 8 and 10 bit version of the ad7924. While we are at it also drop the "with temperature sensor" from the Kconfig entry, since the chips do not have a temperature sensor.

2013-03-17iio:ad7923: Implement scale reportingLars-Peter Clausen1-7/+53
The driver already claims to support scale reporting in its channel spec, but doesn't actually implement this yet. This patch uses the regulator API to get the reference voltage and calculates the scale based on that. The patch also moves the global configuration bits into a field in the ad7923_state struct, since depending on the RANGE bit, the range goes either from 0 to VREF or from 0 to 2 * VREF. So we need to know the setting of the RANGE bit when calculating the scale.
