Subject: [PATCH v2 1/2] touchscreen devicetree binding: Add touchscreen-swap-x-y property
Date: Mon, 23 Feb 2015 17:36:32 +0100	[thread overview]
Message-ID: <1424709393-5838-1-git-send-email-hdegoede@redhat.com> (raw)

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-swap-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.
