* Input: of_touchscreen - add support for inverted / swapped axesHans de Goede2016-07-151-1/+20
| | | | | | | | | | | | | | | 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.

* Input: of_touchscreen - switch to using device propertiesDmitry Torokhov2015-07-111-9/+2
| | | | | | | | Let's switch form OF to device properties so that common parsing code could work not only on device tree but also on ACPI-based platforms. Reviewed-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
* Input: improve parsing OF parameters for touchscreensDmitry Torokhov2015-06-251-2/+3
| | | | | | | | | | When applying touchscreen parameters specified in device tree let's make sure we keep whatever setup was done by the driver and not reset the missing values to zero.

* Input: add common DT binding for touchscreensSebastian Reichel2014-05-291-0/+22
Add common DT binding documentation for touchscreen devices and implement input_parse_touchscreen_of_params, which parses the common properties and configures the input device accordingly. The method currently does not interpret the axis inversion properties, since there is no matching flag in the generic linux input device.
