Add the lcd_device being checked to the check_fb entry of lcd_ops. This
ensures that any driver using this to check against it's own state can do
so, and also makes all the calls in lcd_ops more orthogonal in their
arguments.Signed-off-by: Ben Dooks

As pointed out by Andrew Morton, we have a problem when setting the 64bit
resources option. Alter the allocation routines to remove the need to use
the start and end fields, use the proper HEAD_PANEL/HEAD_CRT and update
the comments.Note, we also fix the bug where we failed to check the size of the
CRT memory allocation.[akpm@linux-foundation.org: cleanup]

Add the ability to register only one of the two possible main framebuffer
devices on the SM501 by passing platform data for only the framebuffer
that you are interested in having.As a side note, we update the init sequence to commonise the code that is
executed twice, and fix a pair of missing frees that we didn't do on
framebuffer exit, such as freeing the fb's cmap.Signed-off-by: Ben Dooks

Avoid division by zero in atmel_lcdfb_check_var() function.
If pixclock is not specified while passing a var structure in
the check_var() funtion, a division by zero occurs (when
translating pixclock to KHz).This patch adds a checking of this value and try to choose a
video mode in the modelist.The mode found in the probe function in added to the modelist.

Remove dead code. This will slightly change the behaviour of the driver
on systems that support backlight control. Previously they would just
turn the backlight off using the backlight control but now the generic LCD
code will also turn off the LCD using the POWER_MANAGEMENT register.Signed-off-by: Olaf Hering

The Kconfig help for the vfb driver says:
Do NOT enable it for normal systems! To protect the innocent, it
has to be enabled explicitly at boot time using the kernel option
`video=vfb:'.This change lets the code match the description.
Support for vfb:disable is kept for backwards compatibility; vfb:off works
because it is tested at a higher level.Note: any undefined option (e.g. vfb:enable) will also enable this driver.
The relevant code has been unchanged since before the migration to
git (2.6.12).This patch fixes bugzilla #9310 and was the root cause behind

This is the SuperH Mobile LCDC frame buffer driver V2, adding support for
the LCDC block found in SuperH Mobile processors. The hardware supports
up to two LCD panels per LCDC block, and both RGB and SYS interfaces can
be used to hook up LCD panels/modules.The device driver is a regular platform driver, so LCD configuration and
board specific hooks are passed to the driver using platform data. LCD
modules using SYS interface often require special configuration using the
SYS bus, and to solve this cleanly the driver provides SYS interface
operations to the board code.Tested on sh7723 and sh7722 processors with a SYS16A QVGA panel and WVGA
panels using RGB16 and RGB18 interfaces.Signed-off-by: Magnus Damm

mdacon incorrectly detects MDA hardware on systems without such graphics card.
One may load this module by chance, for example when doing some systematical
module-testing, and if there is no Monochrome Display Adapter attached ,
module init renders vc1-16 completely unusable.I and others have run into this more than once. see [Bug 224522 - modprobe
mdacon freezes machine -> https://bugzilla.novell.com/show_bug.cgi?id=224522 ]
for exampleApparently proper MDA detection seems to be broken for a long time - seems to
be related to those #ifdef TEST_MDA_B statements added by Edward Betts.this commit back in 2002 made things even worse :
http://git.kernel.org/?p=linux/kernel/git/tglx/history.git;a=commit;h=c72757b49c88914433244757fb4967fc63546685It changed default vc allocation from 13-16 to 1-16 for no apparent reason
(!?) , and with that (and without X), mdacon grabs the vc you`re currently
sitting on and locks you out.this is from Kconfig :
>config MDA_CONSOLE
> depends on !M68K && !PARISC && ISA
> tristate "MDA text console (dual-headed) (EXPERIMENTAL)"
> ---help---
> Say Y here if you have an old MDA or monochrome Hercules graphics
> adapter in your system acting as a second head ( = video card). You
> will then be able to use two monitors with your Linux system. Do not
> say Y here if your MDA card is the primary card in your system; the
> normal VGA driver will handle it.As we can see mdacon is just meant as an additional driver for dual-head
setup, and since kernel 2.4.36 still defaults to vc13-16 , setting the default
back to that value again shouldn`t do any harm.Hereby i'm reverting that change, setting default back to to vc13-16 again.
Besides the fact that mdacon may be rarely or never be used these days and
could perhaps put to trash anyway (pre-dinosaur hardware!), indeed this is not
a real solution, but at least it removes the unfortunate side-effect of
messing up the vc you`re working on.Signed-off-by: Roland Kletzing

This patch fixes following problems:
- does not allow the m parameter to reach 0 as
it locks the graphics core (power cycle needed)
- for the newer chips (with new clock registers)
does not allow of n / m ratio below 4 as it gives
unstable image on the Blade3D core
- extend shift parameter (k) range to 2 for the newer
chips to cope with the n /m >= 4 limit at low resolution
(bandwidth) modes
- prefer modes with higher n / m ratio (higher k values)Signed-off-by: Krzysztof Helt
