From 6ee7c15294985e4e722959fd4482df60cefd2cc8 Mon Sep 17 00:00:00 2001 From: Tom 'spot' Callaway Date: Sun, 24 Apr 2005 20:39:15 -0700 Subject: [PATCH] [SPARC]: TCX Framebuffer fixes Using the same logic as the other framebuffer fixes committed in 2.6.11, this is a set of fixes to make TCX functional on the console again. Adds the tcx_pan_display function, sets the all->info.var.{red,green,blue}.length values to 8, and runs fb_set_cmap. Also looks for the correct SUNW,tcx prom value. This patch just slipped through the cracks. Originally by: Georg Chini Signed-off-by: Tom 'spot' Callaway Signed-off-by: David S.
