++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 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)
++
++The remote will only support the 6 buttons of the original 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.
