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 Boirie
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.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: 3rd round of IIO new drivers, cleanups and functionality for the 3.17 cycle. New drivers * isl29125 digital color light sensor driver * TAOS/AMS tcs3414 digital color sensor Staging graduation * ad7291 ADC driver. New functionality * st_sensors - device tree support and bindings * mma8452 - device tree support Cleanups * Drop redundant variables in a number of drivers. * Reorder a structure definition to ealy wiht a warning about static not being at the beginning in the hid-sensors driver. * Switch a few more drivers away from using explicit sampling_frequency attribute to providing this through the core. * Make hid_sensor_get_reporting_interval static as only used within a single file. * Drop a redundant check for negative values in an unsigned variable from ad9832 * Drop some duplicate case labels in the event monitor example code. * Use devm_ioremap_resource to simplify error handling. * Use devm_kzalloc within the blackfin timer driver to simplify error handling and removal. * A number of cleanups of the ad7291 from Hartmut Knaack in response to a patch moving it out of staging. * Core support for the period info element about events. It has been in the abi for a while, but not added until now to the newer handling of information related to events. * Add HAS_IOMEM dependency to mxs_lradc to avoid build issues when testing enabled.
2014-07-08staging:iio:ad7291: Move out of stagingLars-Peter Clausen
The ad7291 driver is in a reasonable shape. It does not use non-standard API/ABI and there are no major style issues with the driver. So this patch moves it out of staging. There is one small warning from checkpatch which is also fixed in this patch. The patch also sorts the #include directives in alphabetical order.
