Description
***********



.. code-block:: none

   Input longpress pseudo-device

   Listens for key events as an input and produces key events as output
   corresponding to short and long press.

   Can be optionally be associated to a specific device to listen for events
   only from that device.

   Example configuration:

   #include <zephyr/dt-bindings/input/input-event-codes.h>

   longpress {
           input = <&buttons>;
           compatible = "zephyr,input-longpress";
           input-codes = <INPUT_KEY_0>, <INPUT_KEY_1>;
           short-codes = <INPUT_KEY_A>, <INPUT_KEY_B>;
           long-codes = <INPUT_KEY_X>, <INPUT_KEY_Y>;
           long-delay-ms = <1000>;
   };

   Example output:

   # short press
   input event: dev=buttons          SYN type= 1 code= 11 value=1 # INPUT_KEY_0 press
   # release before one second
   input event: dev=buttons          SYN type= 1 code= 11 value=0 # INPUT_KEY_0 release
   input event: dev=longpress        SYN type= 1 code= 30 value=1 # INPUT_KEY_A press
   input event: dev=longpress        SYN type= 1 code= 30 value=0 # INPUT_KEY_A release

   # long press
   input event: dev=buttons          SYN type= 1 code= 11 value=1 # INPUT_KEY_0 press
   # hold for more than one second
   input event: dev=longpress        SYN type= 1 code= 45 value=1 # INPUT_KEY_X press
   # wait for release
   input event: dev=buttons          SYN type= 1 code= 11 value=0 # INPUT_KEY_0 release
   input event: dev=longpress        SYN type= 1 code= 45 value=0 # INPUT_KEY_X release
