3.16.52-rc1 review patch. If anyone has any objections, please let me know.

commit cf5dd48907bebaefdb43a8ca079be77e8da2cb20 upstream.
Step config setting for 5 wire touchscreen is incorrect for Y coordinates. It was broken while we moved to DT. If you look close at the offending commit bb76dc09ddfc ("input: ti_am33x_tsc: Order of TSC wires, made configurable"), the change was:
- STEPCONFIG_XNP | STEPCONFIG_YPN; + ts_dev->bit_xn | ts_dev->bit_yp;
while bit_xn = STEPCONFIG_XNN and bit_yp = STEPCONFIG_YNN. Not quite the same.
