[PATCH] fbdev: geode updates
Geode framebuffer driver updates: - Local mode list (taken from modedb.c) containing only relevant modes. This also makes the driver work as a module. - Make it a PCI driver (from James Simmons <jsimmons@infradead.org>). - A few other minor cosmetic bits and pieces. Signed-off-by: David Vrabel <dvrabel@arcom.com> Signed-off-by: James Simmons <jsimmons@infradead.org> Cc: "Antonino A. Daplas" <adaplas@pol.net> Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Framebuffer driver for the display controller integrated into the

AMD Geode GX1 processor.
|
||||
|
||||
This driver is also available as a module ( = code which can be
|
||||
inserted and removed from the running kernel whenever you want). The
|
||||
module will be called gx1fb. If you want to compile it as a module,
|
||||
say M here and read <file:Documentation/modules.txt>.
|
||||
To compile this driver as a module, choose M here: the module will be
|
||||
called gx1fb.

If unsure, say N.
