[PATCH 03/10] ARM: dts: imx6: RDU2: enable RMI4 reduced reporting

From: Lucas Stach <l.stach@pengutronix.de>
Date: 2021-01-26 21:28:12
Also in: linux-arm-kernel
Subsystem: the rest · Maintainer: Linus Torvalds

To use the reduced reporting mode the threshold values need to be set
explicitly. Configure the threshold to be less than 0.5% of the full
touchscreen range. This seems to be a good compromise between system
load and input accurancy.
