-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.
-
-Tested on a MacbookAir1,1

-Signed-off-by: Bastien Nocera <hadess@hadess.net>

-+Apple IR receiver Driver (appleir)
-+----------------------------------
-+ Copyright (C) 2009 Bastien Nocera <hadess@hadess.net>
-+
-+The appleir driver is a kernel input driver to handle Apple's IR
-+receivers (and associated remotes) in the kernel.
-+
-+The driver is an input driver which only handles "official" remotes
-+as built and sold by Apple.
-+
-+Authors
-+-------
-+
-+James McKenzie (original driver)
-+Alex Karpenko (05ac:8242 support)
-+Greg Kroah-Hartman (cleanups and original submission)
-+Bastien Nocera (further cleanups, brushed metal "enter"
-+button support and suspend support)
-+
-+Supported hardware
-+------------------
-+
-+- All Apple laptops and desktops from 2005 onwards, except:
-+ - the unibody Macbook (2009)
-+ - Mac Pro (all versions)
-+- Apple TV (all revisions prior to September 2010)
-+
-+The remote will only support the 6 (old white) or 7 (brushed metal) buttons
-+of the remotes as sold by Apple. See the next section if you want to use
-+other remotes or want to use lirc with the device instead of the kernel driver.
-+
-+Using lirc (native) instead of the kernel driver
-+------------------------------------------------
-+
-+First, you will need to disable the kernel driver for the receiver.
-+
-+This can be achieved by passing quirks to the usbhid driver.
-+The quirk line would be:
-+usbhid.quirks=0x05ac:0x8242:0x40000010
-+
-+With 0x05ac being the vendor ID (Apple, you shouldn't need to change this)
-+With 0x8242 being the product ID (check the output of lsusb for your hardware)
-+And 0x10 being "HID_QUIRK_HIDDEV_FORCE" and 0x40000000 being "HID_QUIRK_NO_IGNORE"
-+
-+This should force the creation of a hiddev device for the receiver, and
-+make it usable under lirc.
