[PATCH] fbdev: Add helper to get an appropriate initial mode
Add new helper, fb_find_best_display(), which will search the modelist for the best mode for the attached display. This requires an EDID block that is converted to struct fb_monspecs and a private modelist. The search will be done in this manner: - if 1st detailed timing is preferred, use that - else if dimensions of the display are known, use that to estimate xres and - else if modelist has detailed timings, use the first detailed timing - else, use the very first entry from the modelist Signed-off-by: Antonino Daplas <adaplas@pol.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
