From: Jeff Lance <[email protected]>
The step config setting for a 5 wire touchscreen is incorrectly sets the
Y coordinates.
It was broken while we moved to DT. If you look close, 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 :)
Fixes: bb76dc09ddfc ("input: ti_am33x_tsc: Order of TSC wires, made
configurable")
