Merge branch 'x86-fb-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fb changes from Ingo Molnar:
"This tree includes preparatory patches for SimpleDRM driver support,
by David Herrmann. They clean up x86 framebuffer support by creating
simplefb devices wherever possible. More background can be found at
http://lwn.net/Articles/558104/"
* 'x86-fb-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
fbdev: fbcon: select VT_HW_CONSOLE_BINDING
fbdev: efifb: bind to efi-framebuffer
fbdev: vesafb: bind to platform-framebuffer device
fbdev: simplefb: add common x86 RGB formats
x86: sysfb: move EFI quirks from efifb to sysfb
x86: provide platform-devices for boot-framebuffers
fbdev: simplefb: mark as fw and allocate apertures
fbdev: simplefb: add init through platform_data
