From bc2b7dab629a51e8beb5fda4222c62a23b729f26 Mon Sep 17 00:00:00 2001 From: Gregor Boirie Date: Wed, 9 Mar 2016 19:05:49 +0100 Subject: 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.
