I have created a DTS for Beaglebone Black with 4 wire touchscreen and display which works on 3.18 stable and tsc-devel, omap2plus_defconfig with tsc and tilcdc support. It seems that with lcdc disabled, I am not getting false reports but when I'm activating the lcdc, I get a lot of false pen-downs/pen-ups. Even with tilcdc enabled, after it prints "timeout waiting for framedone" and the screen get blanked (white), the noise is gone.
