In order to generate proper key events by overlay buttons and adjust the touch events to a clipped surface, this series offers a documented, device-tree-based solution by means of helper functions. An implementation for a specific touchscreen driver is also included. The functions in touch-overlay provide a simple workflow to acquire physical objects from the device tree, map them into a list and generate events according to the object descriptions. This feature has been tested with a JT240MHQS-E3 display, which consists of an st1624 as the base touchscreen and an overlay with two buttons and a frame that clips its effective surface mounted on it. Signed-off-by: Javier Carrasco --- Changes in v6: - General: use a single list to manage a single type of object. - General: swap patches to have bindings preceding the code. - touch-overlay.c: minor code-sytle fixes. - Link to v5: https://lore.kernel.org/r/20230510-feature-ts_virtobj_patch-v5-0-ff6b5c4db693@wolfvision.net Changes in v5: - touchscreen bindings: move overlay common properties to a $def entry (Rob Herring) - st1232 bindings: move overlays to the existing example instead of making a new one (Rob Herring) - Link to v4: https://lore.kernel.org/r/20230510-feature-ts_virtobj_patch-v4-0-5c6c0fc1eed6@wolfvision.net Changes in v4: - General: rename "touchscreen" to "touch" to include other consumers. - PATCH 1/4: move touch-overlay feature to input core. - PATCH 1/4, 3/4: set key caps and report key events without consumer's intervention. - PATCH 2/4: add missing 'required' field with the required properties. - Link to v3: https://lore.kernel.org/r/20230510-feature-ts_virtobj_patch-v3-0-b4fb7fc4bab7@wolfvision.net Changes in v3: - General: rename "virtobj" and "virtual" to "overlay" - PATCH 1/4: Make feature bool instead of tristate (selected by supported touchscreens) - Link to v2: https://lore.kernel.org/r/20230510-feature-ts_virtobj_patch-v2-0-f68a6bfe7a0f@wolfvision.net Changes in v2: - PATCH 1/4: remove preprocessor directives (the module is selected by the drivers that support the feature). Typo in the commit message. - PATCH 2/4: more detailed documentation.
