Merge tag 'input-for-v6.17-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input updates from Dmitry Torokhov: - updates to several drivers consuming GPIO APIs to use setters returning error codes - an infrastructure allowing to define "overlays" for touchscreens carving out regions implementing buttons and other elements from a bigger sensors and a corresponding update to st1232 driver - an update to AT/PS2 keyboard driver to map F13-F24 by default - Samsung keypad driver got a facelift - evdev input handler will now bind to all devices using EV_SYN event instead of abusing id->driver_info - two new sub-drivers implementing 1A (capacitive buttons) and 21 (forcepad button) functions in Synaptics RMI driver - support for polling mode in Goodix touchscreen driver - support for support for FocalTech FT8716 in edt-ft5x06 driver - support for MT6359 in mtk-pmic-keys driver - removal of pcf50633-input driver since platform it was used on is gone - new definitions for game controller "grip" buttons (BTN_GRIP*) and corresponding changes to xpad and hid-steam controller drivers - a new definition for "performance" key * tag 'input-for-v6.17-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (38 commits) HID: hid-steam: Use new BTN_GRIP* buttons Input: add keycode for performance mode key Input: max77693 - convert to atomic pwm operation Input: st1232 - add touch-overlay handling dt-bindings: input: touchscreen: st1232: add touch-overlay example Input: touch-overlay - add touchscreen overlay handling dt-bindings: touchscreen: add touch-overlay property Input: atkbd - correctly map F13 - F24 Input: xpad - use new BTN_GRIP* buttons Input: Add and document BTN_GRIP* Input: xpad - change buttons the D-Pad gets mapped as to BTN_DPAD_* Documentation: Fix capitalization of XBox -> Xbox Input: synaptics-rmi4 - add support for F1A dt-bindings: input: syna,rmi4: Document F1A function Input: synaptics-rmi4 - add support for Forcepads (F21) Input: mtk-pmic-keys - add support for MT6359 PMIC keys Input: remove special handling of id->driver_info when matching Input: evdev - switch matching to EV_SYN Input: samsung-keypad - use BIT() and GENMASK() where appropriate Input: samsung-keypad - use per-chip parameters ...

List of nodes defining segments (touch areas) on the touchscreen.
93+
94+
This object can be used to describe a series of segments to restrict
95+
the region within touch events are reported or buttons with a specific
96+
functionality.
97+
98+
This is of special interest if the touchscreen is shipped with a physical
99+
overlay on top of it with a frame that hides some part of the original
100+
touchscreen area. Printed buttons on that overlay are also a typical
101+
use case.
102+
103+
A new touchscreen area is defined as a sub-node without a key code. If a
104+
key code is defined in the sub-node, it will be interpreted as a button.
105+
106+
The x-origin and y-origin properties of a touchscreen area define the
107+
offset of a new origin from where the touchscreen events are referenced.
108+
This offset is applied to the events accordingly. The x-size and y-size
109+
properties define the size of the touchscreen effective area.
110+
111+
The following example shows a new touchscreen area with the new origin
112+
(0',0') for the touch events generated by the device.

where (0',0') = (0+x-origin,0+y-origin)
130+
131+
Sub-nodes with key codes report the touch events on their surface as key
132+
events instead.
133+
134+
The following example shows a touchscreen with a single button on it.

Segments defining buttons and clipped toushcreen areas can be combined
150+
as shown in the following example.
151+
In that case only the events within the touchscreen area are reported
152+
as touch events. Events within the button areas report their associated
153+
key code. Any events outside the defined areas are ignored.
