ChangeSet@1.522, 2002-08-14 17:53:32+02:00, vandrove@vc.cvut.cz
  Update matroxfb to current fbdev API.

ChangeSet@1.521, 2002-08-14 16:38:36+02:00, vandrove@vc.cvut.cz
  Set system PLL vcomax correctly in matroxfb. Discovered by Dirk Uffmann.

ChangeSet@1.520, 2002-08-14 16:38:04+02:00, vandrove@vc.cvut.cz
  matroxfb: Do not store results of bitwise AND directly in variables which are
  treated as a booleans. Comparsion does not work correctly on them. 

ChangeSet@1.519, 2002-08-14 16:37:23+02:00, vandrove@vc.cvut.cz
  Add support for MGA-TVO-B into matroxfb. By Mike Pieper.

ChangeSet@1.518, 2002-08-14 16:36:45+02:00, vandrove@vc.cvut.cz
  Return ENOTTY instead of EINVAL for unknown ioctl ops in matroxfb.

ChangeSet@1.517, 2002-08-14 16:36:06+02:00, vandrove@vc.cvut.cz
  Use sizeof(*var) instead of sizeof(struct xxx) in matroxfb.

ChangeSet@1.516, 2002-08-14 16:35:29+02:00, vandrove@vc.cvut.cz
  Remove currcon field from private fb_info in matroxfb. It was moved to the
  generic layer long ago.

ChangeSet@1.515, 2002-08-14 16:34:44+02:00, vandrove@vc.cvut.cz
  Make debug printouts in matroxfb G400 TV-out disabled by default.
  OUTPUT_MODE are values, not a bitmap, so use compare instead of bitwise AND.

ChangeSet@1.514, 2002-08-14 16:32:33+02:00, vandrove@vc.cvut.cz
  Add TV-Out support for Matrox G450/G550. Due to the hardware only secondary
  CRTC can be used as a source for TV output.

ChangeSet@1.513, 2002-08-14 16:30:01+02:00, vandrove@vc.cvut.cz
  matroxfb DVI updates:
  Handle DVI output on G450/G550.
  Powerdown unused portions of G450/G550 DAC.
  Split G450/G550 DAC from older DAC1064 handling.
  Modify PLL setting when both CRTCs use same pixel clocks.

ChangeSet@1.512, 2002-08-14 16:24:08+02:00, vandrove@vc.cvut.cz
  Initialize Matrox G100 and G400 hardware with values read from BIOS instead of
  with failsafe settings discovered in the past.
  Fixes corrupted screen display on some G100.

ChangeSet@1.511, 2002-08-14 16:23:10+02:00, vandrove@vc.cvut.cz
  Use container_of instead of simple typecast when we convert pointers from
  pointer to fb_info to pointers to matrox_fb_info.

ChangeSet@1.510, 2002-08-14 16:21:59+02:00, vandrove@vc.cvut.cz
  Store pointer to matroxfb specific fb information instead of universal
  fb_info* pointer for secondary head. Saves some typecasts.

ChangeSet@1.509, 2002-08-14 16:20:37+02:00, vandrove@vc.cvut.cz
  Use arrays for holding Matrox output drivers, it is nicer and more extensible
  than current solution with per-CRTC bitmaps.

ChangeSet@1.508, 2002-08-14 16:19:37+02:00, vandrove@vc.cvut.cz
  Simplify rules for writting secondary output drivers to matroxfb.
  Update some initializations to use C99 initializers.

ChangeSet@1.507, 2002-08-14 16:11:17+02:00, vandrove@vc.cvut.cz
  matroxfb: Find appropriate setting for specified color depth by looking through
  table instead of using if-else branches in code. Source is cleaner, and generated
  code is smaller with this change. By Denis Zaitsev <zzz@cd-club.ru>

ChangeSet@1.506, 2002-08-14 16:08:09+02:00, vandrove@vc.cvut.cz
  Remove structure holding state of secondary output in the matroxfb driver.
  We do not have any state stored here.

ChangeSet@1.505, 2002-08-14 16:04:20+02:00, vandrove@vc.cvut.cz
  Make secondary output support mandatory for Matrox G450/G550.

ChangeSet@1.504, 2002-08-14 16:01:28+02:00, vandrove@vc.cvut.cz
  Support secondary head DDC on G450/G550.
  Simplify i2c-matroxfb code.
