Subject: [PATCH 03/10] ARM: dts: imx6: RDU2: enable RMI4 reduced reporting
Date: Mon, 25 Jan 2021 19:47:29 +0100 [thread overview]
Message-ID: <20210125184736.1226435-3-l.stach@pengutronix.de> (raw)
In-Reply-To: <20210125184736.1226435-1-l.stach@pengutronix.de>
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.
