From e11e9e78799a7641fe0dc5289f35f2604a4b71a3 Mon Sep 17 00:00:00 2001 From: Bastien Nocera <hadess@hadess.net> Date: Sun, 17 Jan 2010 00:40:15 +0000 Subject: [PATCH] Input: add appleir USB driver 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.
