bc2b7dab62 iio:core: timestamping clock selection support
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.

zero, the change has no effect

e5687979eb iio🔍mag3110 replaces IIO_ST macro with explicit entries to struct scan_type
The IIO_ST macro no longer covers all the elements of struct scan_type
and has this has lead to some bugs being introduced.

The drivers are easier to follow with this structure being directly
filled so that is now preferred.
