From c73314e6ebb2651a70ca8a3ff08d4bd6b9f9ade1 Mon Sep 17 00:00:00 2001 From: Mathieu Othacehe Date: Fri, 20 Jul 2018 19:34:25 +0200 Subject: iio: Add channel for Phase Add new channel type support for phase. This channel may be used by Time-of-flight sensors to express the phase difference between emitted and received signals. Those sensor will then use the phase shift of return signals to approximate the distance to objects.
