From: Hans de Goede Date: Sun, 22 Mar 2015 03:39:19 +0000 (-0700) Subject: Input: touchscreen DT binding - add touchscreen-swapped-x-y property X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=d16a33bb94f88a40a99418993849c1eb93d60de3;p=deliverable%2Flinux.git 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.
