something like

xinput --set-prop --type=float "TSC200X touchscreen" "Coordinate Transformation Matrix"  1.00 0.00 0.00  0.00 1.00 0.00  0.00 0.00 1.00

but I think it is the default of X11 if you use no coordinate transformation at all.
And having the kernel to properly scale from ADC values to screen coordinates.
