From 3055a6cfa04ba4288589778925e8838261e56078 Mon Sep 17 00:00:00 2001 From: Eugen Hristev Date: Tue, 22 May 2018 10:52:32 +0300 Subject: iio: Add channel for Position Relative Add new channel type for relative position on a pad. These type of analog sensor offers the position of a pen on a touchpad, and is represented as a voltage, which can be converted to a position on X and Y axis on the pad. The channel will hand the relative position on the pad in both directions. The channel can then be consumed by a touchscreen driver or read as-is for a raw indication of the touchpen on a touchpad.
