From cf5dd48907bebaefdb43a8ca079be77e8da2cb20 Mon Sep 17 00:00:00 2001 From: Jeff Lance Date: Wed, 18 Oct 2017 17:25:52 -0700 Subject: Input: ti_am335x_tsc - fix incorrect step config for 5 wire touchscreen 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.
