This is from my RPi with touchscreen, it rotates the input device with a transformation matrix, so might be useful to you:

# Touchscreen Rotation am RPi:
# 90 Grad:
#xinput --set-prop 'FT5406 memory based driver' 'Coordinate Transformation Matrix'  0 1 0 -1 0 1 0 0 1
# 180 Grad:
xinput --set-prop 'FT5406 memory based driver' 'Coordinate Transformation Matrix'  -1 0 1 0 -1 1 0 0 1
