From 370d82d3facfb3709c3f4c793229f5b8f5c7001e Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Mon, 25 Jan 2021 19:47:36 +0100 Subject: [PATCH] arm64: dts: zii-rmb3: enable RMI4 reduced reporting 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.
