This driver was originally written by James McKenzie, updated by
Greg Kroah-Hartman, further updated by myself, with suspend support
added.

More recent versions of the IR receiver are also supported through
a patch by Alex Karpenko. The patch also adds support for the 2nd
and 5th generation of the controller, and the menu key on newer
brushed metal remotes.

Tested on a MacbookAir1,1

Resend, as the original patch never made it. I cleaned up the patch a
bit further, and test compiled it, but didn't have a chance to test it
as I don't have a machine with that hardware available anymore.

Fabien, in CC, gracefully accepted to test and to try to adapt this
patch depending on the reviews. So we can ask for tests and changes!

not sure we should change this define to an undocumented one.

I don't understand the comment here. The name is an artifact of where
the receiver was first seen and the Apple TV receiver is actually just
another model of this same receiver. So it makes sense to consolidate
below.

why this keymap is embedded in the struct? It's basically just a copy
of appleir_key_table and it's not modified anytime.

It would be modified if you change the keymap.
