The remove member of the platform_driver bfin_t350mcqb_driver should use
__devexit_p() to refer to the remove function, and that function should
get __devexit markings. Likewise, the probe function should be marked
with __devinit and not __init.
Also, module_init() functions should be marked with __init rather than
__devinit.

is no need to call memset after the allocation. Also no point in clearing

Add accelerated bitblt functions to s1d13xxx based video chipsets, more
specificly functions copyarea and fillrect.
It has only been tested and activated for 13506 chipsets but is expected
to work for the majority of s1d13xxx based chips. This patch also cleans
up the driver with respect of whitespaces and other formatting issues. We
update the current status comments.

With KMS we have ran into an issue where we really want the KMS fb driver
to be the one running the console, so panics etc can be shown by switching
out of X etc.
However with vesafb/efifb built-in, we end up with those on fb0 and the
KMS fb driver on fb1, driving the same piece of hw, so this adds an fb
info flag to denote a firmware fbdev, and adds a new aperture base/size
range which can be compared when the hw drivers are installed to see if
there is a conflict with a firmware driver, and if there is the firmware
driver is unregistered and the hw driver takes over.
It uses new aperture_base/size members instead of comparing on the fix
smem_start/length, as smem_start/length might for example only cover the
first 1MB of the PCI aperture, and we could allocate the kms fb from 8MB
into the aperture, thus they would never overlap.

When changing video timing dynamically via fbset the screen sporadically
is rendered black.
With the attached fix which disables VCO prior to timing register change
the problem disappears.
I had a look at the Xserver register setup code. Here the VCO is
disabled in the same way [1].

The driver's fb_mmap function is essentially the same as a generic fb_mmap
function. Delete driver's function and use the generic one.
A difference is that generic function marks frame buffer memory as VM_IO |
VM_RESERVED. The driver's function marks it as VM_IO only.

Add support for the ARGB1888 and ARGB4888 hardware to the Samsung SoC
Framebuffer driver (s3c-fb.c).
ARGB1888 and ARGB4888 is decided by var->transp.length and this variable
is set by s3c_fb_check_var().
In s3c_fb_check_var(), if var->vits_per_pixel is 25 or 28, then
var->transp.length would be 1 or 3.
Therefore alpha mode(ARGB1888 or ARGB4888) could be decided through that
variable.
For using alpha mode, you need to set the following: This code should be
added to your machine code as platform data.
static struct s3c_fb_pd_win xxx_fb_win0 = {
/* this is to ensure we use win0 */
.win_mode = {
.pixclock = (8+8+8+240)*(38+4+38+400),
.left_margin = 8,
.right_margin = 8,
.upper_margin = 38,
.lower_margin = 38,
.hsync_len = 8,
.vsync_len = 4,
.xres = 240,
.yres = 400,
},
.max_bpp = 32,
.default_bpp = 24,
};
static struct s3c_fb_pd_win xxx_fb_win1 = {
.win_mode = {
.pixclock = (8+8+8+240)*(38+4+38+400),
.left_margin = 8,
.right_margin = 8,
.upper_margin = 38,
.lower_margin = 38,
.hsync_len = 8,
.vsync_len = 4,
.xres = 240,
.yres = 400,
},
.max_bpp = 32,
.default_bpp = 28,
};
static struct s3c_fb_platdata xxx_lcd_pdata __initdata = {
.win[0] = &ncp_fb_win0,
.win[1] = &ncp_fb_win1,
.vidcon0 = VIDCON0_VIDOUT_RGB | VIDCON0_PNRMODE_RGB,
.vidcon1 = VIDCON1_INV_HSYNC | VIDCON1_INV_VSYNC,
.setup_gpio = xxx_fb_gpio_setup,
};
s3c_fb_set_platdata(&xxx_lcd_pdata);
The above code sets pixelformat for window0 layer to RGB888 and window1
layer to ARGB4888.

AFAICT the code which checks that the requested pixclock value is within
bounds is incorrect. It ensures that the lcdc core clock is at least
(bytes per pixel) times higher than the pixel clock rather than just
greater than or equal to.
There are tighter restrictions on the pixclock value as a function of bus
width for STN panels but even then it isn't a simple relationship as
currently checked for. IMO either something like the below patch should
be applied or else more detailed checking logic should be implemented
which takes in to account the panel type as well.

In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device. Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used. These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

There's no point in giving the I2C bus of Voodoo3 adapters a class
value, there's no video chip driver checking for it anymore. If
support is ever needed, the video device should be instantiated
explicitly rather than probed.
To the best of my knowledge the only video chip that can be found on
these boards is a BT869 video encoder, for which no support exists
currently.

This driver is originally written by Lennert, modified by Green to be
feature complete, and ported by Jun Nie and Kevin Liu for pxa168/910
processors.
The patch adds support for the on-chip LCD display controller, it
currently supports the base (graphics) layer only.

1) Now module_param(..., invbool, ...) requires a bool, and similarly
module_param(..., bool, ...) allows it, change pmi_setpal to a bool.
2) #define param_get_scroll to NULL, since it can never be called (perm
argument to module_param_named is 0).
3) Return -EINVAL from param_set_scroll if the value is bad, so it's
reported.
Note that I don't think the old fb_get_options() is required for new
drivers: the parameters automatically work as uvesafb.XXX=... anyway.

Since 2.4, the correct answer has been to not define an unload fn.

I found the PrimeCell/AMBA Bus drivers distrusting the resource
passed in as part of the struct amba_device abstraction. This
patch removes all hard coded resource sizes found in the PrimeCell
drivers and move the responsibility of this definition back to
the platform/board device definition, which already exist and
appear to be correct for all in-tree users of these drivers.
We do this using the resource_size() inline function which was
also replicated in the only driver using the resource size, so
that has been changed too. The KMI_SIZE was left in kmi.h in case
someone likes it. Test-compiled against Versatile and Integrator
defconfigs, seems to work but I don't posess these boards and
cannot test them.

Added support for the new xps tft controller. The new core
has PLB interface support in addition to existing DCR interface.
Removed platform device support as both MicroBlaze and PowerPC
use device tree.
Previously, the dcr interface was assumed to be used in mmio mode,
and the register space of the dcr interface was precomputed and stuffed
into the device tree. This driver now makes use of the new dcr
infrastructure to represent the dcr interface. This enables the dcr
interface to be connected directly to a native dcr interface in a clean
way.
Added compatibility for ml507 dvi core.

The software fillrect routines do not work properly when the number of
pixels per machine word is not an integer. To see that, run the following
command on a fbdev console with a 24bpp video mode, using a
non-accelerated driver such as (u)vesafb:
reset ; echo -e '\e[41mtest\e[K'
The expected result is 'test' displayed on a line with red background.
Instead of that, 'test' has a red background, but the rest of the line
(rendered using fillrect()) contains a distored colorful pattern.
This patch fixes the problem by correctly computing rotation shifts. It
has been tested in a 24bpp mode on 32- and 64-bit little-endian machines.

Uwe Geuder noted that he gets random bitmaps on a text console if he tried
to type extended characters (like the e acute). For him everything above
unicode 0xa0 was corrupted.
After some digging there seems to be a little culprit in vgacon since the
beginning of ages (well git). The function vgacon_font_get will store the
number of characters correctly in font->charcount but then calls to
vgacon_do_font_op(..., 0, 0). Which means only the lower 256 characters
are actually stored to the fontdata. The rest is left untouched. So the
next time that saved data is used, the garbled font appears. This happens
on every switch between text consoles.
