If implemented properly, key code tables can be replaced anytime in
We have already a tool for this, under v4l2-apps/util. It is called
keytable. The tool can be used to get the current key association of an
input device, generating a text file, or to load a text file into an input
When you build the tool, the Makefile will parse several keycode tables
already existing on V4L and at the common IR files, writing them into
keycodes/ dir. It would be really easy to parse other files and create
their tables as well.
