Input: include export.h in modules using EXPORT_SYMBOL*()

2025-08-21T19:00:59Z

A number of modules in the input subsystem use EXPORT_SYMBOL() and friends without explicitly including the corresponding header . While the build currently succeeds due to this header being pulled in transitively, this is not guaranteed to be the case in the future. Let's add the explicit include to make the dependencies clear and prevent future build breakage. Signed-off-by: Dmitry Torokhov

Input: synaptics-rmi4 - remove the exporting of rmi_2d_sensor_set_input_params

2019-07-24T09:58:11Z

The function rmi_2d_sensor_set_input_params is declared static and marked EXPORT_SYMBOL_GPL, which is at best an odd combination. Because the function is not used outside of the drivers/input/rmi4/rmi_2d_sensor.c file it is defined in, this commit removes the EXPORT_SYMBOL_GPL() marking.

Input: synaptics-rmi4 - fix axis-swap behavior

2018-06-11T17:20:16Z

The documentation for the touchscreen-swapped-x-y property states that swapping is done after inverting if both are used. RMI4 did it the other way around, leading to inconsistent behavior with regard to other touchscreens. Signed-off-by: Lucas Stach Tested-by: Nick Dyer Signed-off-by: Dmitry Torokhov

Input: synaptics-rmi4 - correctly swap clip values if axes are swapped

2017-01-15T23:41:00Z

The clip values need the same swapping as the maximum values if the sensor axes are swapped. Signed-off-by: Lucas Stach Signed-off-by: Dmitry Torokhov

Input: synaptics-rmi4 - set the ABS_MT_TOOL_TYPE bit to report tool type

2016-11-09T01:12:09Z

The rmi4 2D sensor functions report the tool type via input_mt_report_slot_state(), but the abs parameter bit has not been set so the tool type is not reported to userspace. This patch set the ABS_MT_TOOL_TYPE bit. Signed-off-by: Andrew Duggan Signed-off-by: Benjamin Tissoires Signed-off-by: Dmitry Torokhov

Input: synaptics-rmi4 - add device tree support for 2d sensors and F11

2016-03-11T00:04:05Z

2D sensors have several parameter which can be set in the platform data. This patch adds support for getting those values from devicetree. Signed-off-by: Andrew Duggan Tested-by: Benjamin Tissoires Tested-by: Linus Walleij Tested-by: Bjorn Andersson Signed-off-by: Dmitry Torokhov

Input: synaptics-rmi4 - add support for 2D sensors and F11

2016-03-11T00:04:03Z

RMI4 currently defines two functions for reporting data for 2D sensors (F11 and F12). This patch adds the common functionality which is shared by devices with 2D reporting along with implementing functionality for F11.
