-*
-* Copyright (C) 1998 Alan Bair

-* This file is based on two CyberVision64 frame buffer device drivers
-*
-* The second CyberVision64 frame buffer device (cvision.c cvision_core.c):
-*
-* Copyright (c) 1997 Antonio Santos
-*
-* Released as a patch to 2.1.35, but never included in the source tree.
-* This is based on work from the NetBSD CyberVision64 frame buffer driver
-* and support files (grf_cv.c, grf_cvreg.h, ite_cv.c):
-* Permission to use the source of this driver was obtained from the
-* author Michael Teske by Alan Bair.

-*
-* Which is based on the Amiga frame buffer device (amifb.c):

-* History:
-* - 22 Dec 95: Original version by Martin Apel
-* - 05 Jan 96: Geert: integration into the current source tree
-* - 01 Aug 98: Alan: Merge in code from cvision.c and cvision_core.c
-* $Log: cyberfb.c,v $
-* Revision 1.6 1998/09/11 04:54:58 abair
-* Update for 2.1.120 change in include file location.
-* Clean up for public release.
-*
-* Revision 1.5 1998/09/03 04:27:13 abair
-* Move cv64_load_video_mode to cyber_set_video so a new video mode is install
-* with each change of the 'var' data.
-*
-* Revision 1.4 1998/09/01 00:31:17 abair
-* Put in a set of default 8,16,24 bpp modes and map cyber8,16 to them.
-* Update operations with 'par' to handle a more complete set of parameter
-* values for encode/decode process.
-*
-* Revision 1.3 1998/08/31 21:31:33 abair
-* Swap 800x490 for 640x480 video mode and more cleanup.
-* Abandon idea to resurrect "custom" mode setting via kernel opts,
-* instead work on making use of fbset program to do this.
-*
-* Revision 1.2 1998/08/31 06:17:08 abair
-* Make updates for changes in cyberfb.c released in 2.1.119
-* and do some cleanup of the code.
-*
-* Revision 1.1 1998/08/29 18:38:31 abair
-* Initial revision
-*
-* Revision 1.3 1998/08/17 06:21:53 abair
-* Remove more redundant code after merging in cvision_core.c
-* Set blanking by colormap to pale red to detect this vs trying to
-* use video blanking. More formating to Linux code style.
-*
-* Revision 1.2 1998/08/15 17:51:37 abair
-* Added cvision_core.c code from 2.1.35 patches.
-* Changed to compile correctly and switch to using initialization
-* code. Added debugging and dropping of duplicate code.

- * A small info on how to convert XFree86 timing values into fb
- * timings - by Frank Neumann:
- *
-An XFree86 mode line consists of the following fields:
- "800x600" 50 800 856 976 1040 600 637 643 666
- < name > DCF HR SH1 SH2 HFL VR SV1 SV2 VFL
-
-The fields in the fb_var_screeninfo structure are:
- unsigned long pixclock; * pixel clock in ps (pico seconds) *
- unsigned long left_margin; * time from sync to picture *
- unsigned long right_margin; * time from picture to sync *
- unsigned long upper_margin; * time from sync to picture *
- unsigned long lower_margin;
- unsigned long hsync_len; * length of horizontal sync *
- unsigned long vsync_len; * length of vertical sync *
-
-1) Pixelclock:
- xfree: in MHz
- fb: In Picoseconds (ps)
-
- pixclock = 1000000 / DCF
-
-2) horizontal timings:
- left_margin = HFL - SH2
- right_margin = SH1 - HR
- hsync_len = SH2 - SH1
-
-3) vertical timings:
- upper_margin = VFL - SV2
- lower_margin = SV1 - VR
- vsync_len = SV2 - SV1
-
-Good examples for VESA timings can be found in the XFree86 source tree,
-under "programs/Xserver/hw/xfree86/doc/modeDB.txt".
