mb/lenovo/w520: Add ThinkPad W520 support
Tested and working:
* 4 RAM-slots
* Speakers
* PCIe Wifi
* Camera
* Fan
* Touchpad, trackpoint and keyboard
* Ethernet
* Keyboard ACPI events
* USB 3.0
* SD-card reader
* Native graphics (LCD panel)
* Harddisk in Ultrabay
* SeaBIOS payloads
** Debian Live
** Debian testing 4.14.0-3-amd64
* GRUB
** Debian Live
** Debian testing 4.14.0-3-amd64
Not working:
* Displayport and VGA output (requires VGA option ROM and ACPI switch call)
Not tested:
* Intel VGA option ROM
* ACPI events related to ultrabay
* Smart card reader
* Docking station
