Nicolas Ferre 1434058614 atmel_lcdfb: AT91/AT32 LCD Controller framebuffer driver
Adds a framebuffer driver to ATMEL AT91SAM9x and AT32 aka AVR32 platforms.
Those chips share quite the same IP and this code is suitable for both
architectures.

Krzysztof Helt f23a06f076 pm3fb: Preliminary 2.4 to 2.6 port
This is a basic port from 2.4 kernel to 2.6.  Acceleration is lost and big
endian support probably too.  The driver works in 8, 16 and 32 bit mode.

[adaplas]
- change VESA_* to FB_BLANK_* constants
- removed unused function clear_memory
- fix uninitialized variable compiler warning
- some whitespace cleaning

Maciej W. Rozycki 86c6f7d08b tgafb: TURBOchannel support
This is support for the TC variations of the TGA boards (properly known as
SFB+ or Smart Frame Buffer Plus boards).  The 8-plane SFB+ board uses the
Bt459 RAMDAC (unlike its PCI TGA counterpart, which uses the Bt485), so
bits have been added to support this chip as well.

Adrian Bunk 52e7c922f3 [PATCH] remove the broken FB_S3TRIO driver
The FB_S3TRIO driver:
- has been marked as BROKEN for more than two years and
- is still marked as BROKEN.

Drivers that had been marked as BROKEN for such a long time seem to be
unlikely to be revived in the forseeable future.

But if anyone wants to ever revive this driver, the code is still
present in the older kernel releases.

This patch adds a way to create and use the video plane (YUV overlay) and
scaling video scaling features of the chip.

The overlay is configured, resized and modified using a device specific
ioctl.

Also included in this patch:
  - If no platform data was passed, print an error and exit instead of crashing.
  - Added a write_reg(_dly) macro. This improves readability when
    manipulating chip registers. (no more udelay() after each write).
  - Comments about some issues.

Christian Trefzer 9f672004ab [PATCH] neofb: avoid resetting display config on unblank (v2)
There were two mistakes in the register-read-on-(un)blank approach.

- First, without proper register (un)locking the value read back will always
  be zero, and this is what I missed entirely until just now.  Due to this,
  the logic could not be verified at all and I tried some bogus checks which
  are completely stupid.

- Second, the LCD status bit will always be set to zero when the backlight
  has been turned off.  Reading the value back during unblank will disable the
  LCD unconditionally, regardless of the state it is supposed to be in, since
  we set it to zero beforehand.

So this is what we do now:

- create a new variable in struct neofb_par, and use that to determine
  whether to read back registers (initialized to true)

- before actually blanking the screen, read back the register to sense any
  possible change made through Fn key combo

- use proper neoUnlock() / neoLock() to actually read something

- every call to neofb_blank() determines if we read back next time: blanking
  disables readback, unblanking (FB_BLANK_UNBLANK) enables it

This should give us a nice and clean state machine.  Has been thoroughly
tested on a Dell Latitude CPiA / NM220 Chip docked to a C/Dock2 with attached
CRT in all possible combinations of LCD/CRT on/off.  I changed the config via
Fn key, let the console blank, unblanked by keypress - works flawlessly.

Knut Petersen 44637a12f8 [PATCH] Update cyblafb driver
This is a major update to the cyblafb framebuffer driver. Most
of the stuff has been tested in the mm tree.

Main advantages:
============
  - vxres > xres support
  - ywrap and xpan support
  - much faster for almost all modes (e.g. 1280x1024-16bpp
     draws more than 41 full screens of text instead of about 25
     full screens of text per second on authors Epia 5000)
  - module init/exit code fixed
  - bugs triggered by console rotation fixed
  - lots of minor improvements
  - startup modes suitable for high performance scrolling
     in all directions

This diff  also contains a lot of white space fixes.

No side effects are possible, only one single graphics core is affected.

Knut Petersen 9fa68eae9f [PATCH] framebuffer: new driver for cyberblade/i1 graphics core
This is a framebuffer driver for the Cyberblade/i1 graphics core.

Currently tridenfb claims to support the cyberblade/i1 graphics core.  This
is of very limited truth.  Even vesafb is faster and provides more working
modes and a much better quality of the video signal.  There is a great
number of bugs in tridentfb ...  but most often it is impossible to decide
if these bugs are real bugs or if fixing them for the cyberblade/i1 core
would break support for one of the other supported chips.

Tridentfb seems to be unmaintained,and documentation for most of the
supported chips is not available.  So "fixing" cyberblade/i1 support inside
of tridentfb was not an option, it would have caused numerous
if(CYBERBLADEi1) else ...  cases and would have rendered the code to be
almost unmaintainable.

A first version of this driver was published on 2005-07-31.  A fix for a
bug reported by Jochen Hein was integrated as well as some changes
requested by Antonino A.  Daplas.

A message has been added to tridentfb to inform current users of tridentfb
to switch to cyblafb if the cyberblade/i1 graphics core is detected.

This patch is one logical change, but because of the included documentation
it is bigger than 70kb.  Therefore it is not sent to lkml and
linux-fbdev-devel,

Thomas Winischhofer 544393fe58 [PATCH] sisfb update
This lifts sisfb from version 1.7.17 to version 1.8.9. Changes include:

- Added support for XGI V3XT, V5, V8, Z7 chipsets, including POSTing of
  all of these chipsets.

- Added support for latest SiS chipsets (761).

- Added support for SiS76x memory "hybrid" mode.

- Added support for new LCD resolutions (eg 1280x854, 856x480).

- Fixed support for 320x240 STN panels (for embedded devices).

- Fixed many HDTV modes (525p, 750p, 1080i).

- Fixed PCI config register reading/writing to use proper kernel
  functions for this purpose.

- Fixed PCI ROM handling to use the kernel's proper functions.

- Removed lots of "typedef"s.

- Removed lots of code which was for X.org/XFree86 only.

- Fixed coding style in many places.

- Removed lots of 2.4 cruft.

- Reduced stack size by unifying two previously separate structs into
  one.

- Added new hooks for memory allocation (for DRM).  Now the driver can
  truly handle multiple cards, including memory management.

- Fixed numerous minor bugs.

Richard Purdie aac51f09d9 [PATCH] w100fb: Rewrite for platform independence
The code w100fb was based on was horribly Sharp SL-C7x0 specific and there
was little else that could be done as I had no access to anything else with
a w100 in it.  There is no real documentation about this chipset available.

Ian Molton has access to other platforms with the w100 (Toshiba e-series)
and so between us, we've improved w100fb and made it platform independent.
Ian Molton also added support for the very similar w3220 and w3200
chipsets.

There are a lot of changes here and it nearly amounts to a rewrite of the
driver but it has been extensively tested and is being used in preference
to the original driver in the Zaurus community.  I'd therefore like to
update the mainline code to reflect this.
