From 57c80e8e5d1cddae0651e5314394e6069ebbbe3c Mon Sep 17 00:00:00 2001 From: Karsten Merker Date: Thu, 17 Dec 2015 17:08:31 -0800 Subject: Input: goodix - use "inverted_[xy]" flags instead of "rotated_screen" The goodix touchscreen driver uses a "rotated_screen" flag for systems on which the touchscreen is mounted rotated by 180 degrees with respect to the display. With the addition of support for the dt properties "touchscreen-inverted-x" and "touchscreen-inverted-y", a separate "rotated_screen" flag is not necessary anymore. This patch replaces it by setting the inverted_x and inverted_y flags instead.
