From a96cd0f901eecd9589477cc2cd46bdb4f1f3e49a Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Mon, 28 Nov 2016 14:41:16 -0800 Subject: iio: accel: hid-sensor-accel-3d: Add timestamp Added timestamp channel. With this change, each sample has a timestamp. This timestamp can be from the sensor hub when present or local kernel timestamp. HID sensors can send timestamp with input data using usage id HID_USAGE_SENSOR_TIME_TIMESTAMP. This timestamp value is converted to nano seconds before pushing this sample to the iio core.
