Subject: ARM: dts: imx6: RDU2: enable RMI4 reduced reporting
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=20fffe76b6241d691a92f8d2fc0092da707dde67;p=linux.git

ARM: dts: imx6: RDU2: 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.
