From ed7c9870c9bc6ca50dc0d271a301410bc894f4b9 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Fri, 15 Jul 2016 14:05:29 -0700 Subject: Input: of_touchscreen - add support for inverted / swapped axes Extend touchscreen_parse_properties() with support for the touchscreen-inverted-x/y and touchscreen-swapped-x-y properties and add touchscreen_set_mt_pos() and touchscreen_report_pos() helper functions for storing coordinates into a input_mt_pos struct, or directly reporting them, taking these properties into account. This commit also modifies the existing callers of touchscreen_parse_properties() to pass in NULL for the new third argument, keeping the existing behavior.
