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.Signed-off-by: Maciej W. Rozycki

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.Signed-off-by: Adrian Bunk

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.Signed-off-by: Raphael Assenat

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 itThis 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.Signed-off-by: Christian Trefzer

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 directionsThis diff also contains a lot of white space fixes.
No side effects are possible, only one single graphics core is affected.

Separate out the Sharp Zaurus c7x0 series specific code from the Corgi
Touchscreen driver. Use the new functions in corgi_lcd.c via sharpsl.h for
hsync handling and pass the IRQ as a platform device resource. Move a
function prototype into the w100fb header file where it belongs.This enables the driver to be used by the Zaurus cxx00 series.

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,Signed-off-by: Knut Petersen

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.

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.Signed-off-by: Richard Purdie

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
