From d16a33bb94f88a40a99418993849c1eb93d60de3 Mon Sep 17 00:00:00 2001 From: Hans de Goede <hdegoede@redhat.com> Date: Sat, 21 Mar 2015 20:39:19 -0700 Subject: [PATCH] Input: touchscreen DT binding - add touchscreen-swapped-x-y property On devices with a native portrait screen a landscape touchscreen / digitizer may be used, this happens e.g. on ebook readers. In this case the X and Y axis of the touchscreen are swapped compared to the screen. Add a touchscreen-swapped-x-y property which drivers can use to see if they need to swap the axis to make the touchscreen coordinates match the screen coordinates.
