Infrared remote control support in video4linux drivers
======================================================
Authors: Gerd Hoffmann, Mauro Carvalho Chehab
Basics
-------
+======
Most analog and digital TV boards support remote controllers. Several of
them have a microprocessor that receives the IR carriers, convert into
ir-kbd-i2c module.
How it works
-------------
+============
The modules register the remote as keyboard within the linux input
layer, i.e. you'll see the keys of the remote as normal key strokes
Using with lircd
-================
+----------------
The latest versions of the lircd daemon supports reading events from the
linux input layer (via event device). It also supports receiving IR codes
Using without lircd
-===================
+-------------------
Xorg recognizes several IR keycodes that have its numerical value lower
than 247. With the advent of Wayland, the input driver got updated too,
