viafb: use read-only mode parsing

The previous method of mode parsing wrote to the strings resulting in
truncated mode strings in the sysfs.

31de59d5e1 viafb: hardware acceleration initialization cleanup
The main motivation of this patch was to merge the three initialization
functions in one and clean it up. However as some changes in other code
areas where needed to do it right some small other changes were made.

Changes to viafb_par:

io_virt renamed as engine_mmio and moved to shared
VQ_start renamed as vq_vram_addr and moved to shared
VQ_end removed as it is easily recalculatable

vq_vram_addr is not strictly needed but keep it to track where we
allocated video memory.  The memory allocated for the virtual queue was
shrunk to VQ_SIZE as VQ_SIZE+CURSOR_SIZE looked like a bug to me.  But to
be honest I don't have the faintest idea what virtual queues are for in
the graphic hardware and whether the driver needs them in any way.  I only
know that they aren't directly accessed by the driver and so the only
potential current use would be as hardware internal buffers.  For now keep
them to avoid regressions and only remove the double cursor allocation.

The most changes were caused by renames and the mentioned structure
changes so the chance of regressions is pretty low.  The meaning of
viafb_accel changed slightly as previously it was changed back and forth
in the code and allowed to enable the hardware acceleration by software if
previously disabled.  The new behaviour is that viafb_accel=0 always
prevents hardware acceleration.  With viafb_accel!=0 the acceleration can
be freely choosen by set_var.  This means viafb_accel is a diagnostic tool
and if someone has to use viafb_accel=0 the driver needs to be fixed.

As this is mostly a code cleanup no regressions beside the slightly change
of viafb_accel is expected.

2d6e8851f6 viafb: improve pitch handling
Split the pitch handling up and replaces the calculation from virtual xres
and bpp with fix.line_length which already contains the pitch and does not
add any constrains for the virtual resolution.

Also add a bit to the second pitch which the documentation mentions but
which was ignored by the driver.

Although it is a bit unclear what the right pitch for some LCD modes is
this patch should have no negative runtime impact.

5016af53eb viafb: cleanup viafb_cursor
Clean the hardware cursor handling up.

The most notable change is that it no longer buffers the values in
viacursor but uses the ones in cursor instead as they are guaranteed to be
always valid.

Furthermore it uses local instead global variables where possible, moves
the cursor variable in shared as only one hardware cursor is supported and
returns an error if memory allocation fails.  Last but not least it fixes
a too small buffer (as u32 has only 4 and not 32 bytes) but this did not
produce any known problems.

This is mostly a code cleanup, no negative runtime changes are expected.

c3e2567384 viafb: 2D engine rewrite
This patch is a completly rewritten 2D engine.  The engine is no longer in
a default state but reinitialized every time to allow usage for both
framebuffers regardless of their settings.

The whole engine handling is concentrated in a big function which takes 16
parameters.  Although the number of parameters is worryingly it is good to
have a single funtion to deal with this stuff as it allows to easily
support different engines and avoids some code duplication.

On the way support for the new 2D engine in VX800 was added.  As the with
less code duplication but it is probably better to duplicate the code as
this way is easier to walk if VIA ever decides to release a new engine
which changes anything the driver touches.

The engine support for VX800 gives a notable boost in speed.  There are no
known regressions but as this patch changes paths I do neither have the
hardware nor documentation to check and has the possibility to put the
system in a critical state heavy testing is appreciated.

c4df5489e4 viafb: improve viafb_par
This patch introduces viafb_shared and is the beginning of a smooth
transition to use it.

viafb_shared should contain all general, non-surface specific data that
should be shared along all viafb framebuffers while viafb_par should only
contain things that are specific to each surface or in other words extend
fb_info.  This change is intended to clean the dual/multi framebuffer
handling up.

This removes the annoyance that viafbinfo1->par points to a different
structure than viaparinfo1.

As the last change is fundamental it is difficult to ensure that all parts
of the driver do not depend on the previous brokenness but the chance of
regressions is very low.

8594ac3345 viafb: remove LVDS initialization
At least for VX800 this initialization is not very good as some parts of
the register are written with reserved values.  This makes the display go
white in some configurations and not usable until the framebuffer is
removed.  It's better to not initialize it as it allows to use a
previously (by BIOS) correctly configured display.

This patch makes some displays work but might cause problems on others.
This is bad but can not be easily avoided.  If this causes some
regressions it's probably the best to fix it in the 'active' display setup
code.

b852abc263 viafb: remove unused video device stuff
Remove everything related to video devices from the driver as it did not
influence the driver operation.  This patch does change the userspace
behaviour as it removes two IOCTLs and one module parameter.  But this is
good as it removes useless stuff and helps the user to figure out the
options that do affect the driver behaviour (which are still too many).

db88e382a0 viafb: clean up virtual memory handling
Clean the handling of ioremapped video memory up.  The following changes
were made:

info->screen_base - viafb_FB_MM
(VRAM offset calculation) was replaced by
info->fix.smem_start - viafbinfo->fix.smem_start
which is essentially the same calculation but done with physical instead
virtual addresses.

*->fbmem_virt
was replaced by
viafbinfo->screen_base
This is true for viafbinfo and viafbinfo1 as the par pointers are equal.

An early initialization of viafbinfo1->fix.smem* was removed as done later
in viafb_setup_fixinfo.

This patch highlights that the only usage of the ioremapped video memory
in the driver is for hardware cursor handling.  Even if it has to hold the
used virtual screen mapped for old-fashioned read/write calls (vs.
mmap'ed) a lot virtual memory could be saved by only ioremapping on
demand.

Code cleanup, no runtime changes expected.

13147f291c viafb: remove duplicated mode information
Remove the mode information from viafbdev.c and uses the one of viamode.c
instead.  This is possible because horizontal and vertical address are the
same as horizontal and vertical resolution.  The reduced blanking modes in
the table are no problem because they have a higher index than the normal
modes and therefore always the normal modes are selected just as the old
behaviour.

09cf11806e viafb: split viafb_set_start_addr up
Move individual start address setting to viafb_set_primary_address and
viafb_set_secondary_address and make it more flexible to reuse it for
panning.  Using central functions makes it easier to follow HW
manipulations.

Remove crt locking as it should be only needed for timing manipulation.
Move iga_path manipulation to via_pci_probe.

Remove memset for screen cleaning as it is currently done only for the
second screen.  This is not needed for normal operation but has a little
chance of causing unwanted display artifacts.  This can be fixed later
more consistent and more efficient (using viafb_fillrect) if needed.

This is a code clenup, no notable runtime changes expected.

This is not done consistently along graphic cores and not even the whole

later.

LCDC on DA8xx consists of two independent controllers, the Raster
Controller and the LCD Interface Display Driver (LIDD) controller.  LIDD
further supports character and graphic displays.

This patch adds support for the graphic display (Sharp LQ035Q3DG01) found
on the DA830 based EVM.  The EVM details can be found at:

4c88ef170f omapfb: dispc: allow multiple external IRQ handlers
Previously, the only external (to dispc.c) IRQ handler was RFBI's frame
done handler.  dispc's IRQ framework was very dumb: you could only have
one handler, and the semantics of {request,free}_irq were odd, to say the
least.

The new framework allows multiple consumers to register arbitrary IRQ
masks.

f9e2bc8d7b omapfb: dispc: disable iface clocks along with func clocks
Leaving interface clocks enabled causes dss pwrdm to stay in active state
when mpu is in active state.  This fix puts dss to sleep state when it is
not needed.

Earlier version broke framebuffer on 24xx.  This is fixed by enabling
clocks before trying to access DISPC_IRQSTATUS register.

09d3f3f0e0 sparc: Kill PROM console driver.
Many years ago when this driver was written, it had a use, but these
days it's nothing but trouble and distributions should not enable it
in any situation.

Pretty much every console device a sparc machine could see has a
bonafide real driver, making the PROM console hack unnecessary.

If any new device shows up, we should write a driver instead of
depending upon this crutch to save us.  We've been able to take care
of this even when no chip documentation exists (sunxvr500, sunxvr2500)
so there are no excuses.

deb2d2ecd4 PCI/GPU: implement VGA arbitration on Linux
Background:
Graphic devices are accessed through ranges in I/O or memory space. While most
modern devices allow relocation of such ranges, some "Legacy" VGA devices
implemented on PCI will typically have the same "hard-decoded" addresses as
they did on ISA. For more details see "PCI Bus Binding to IEEE Std 1275-1994
Standard for Boot (Initialization Configuration) Firmware Revision 2.1"
Section 7, Legacy Devices.

The Resource Access Control (RAC) module inside the X server currently does
the task of arbitration when more than one legacy device co-exists on the same
machine. But the problem happens when these devices are trying to be accessed
by different userspace clients (e.g. two server in parallel). Their address
assignments conflict. Therefore an arbitration scheme _outside_ of the X
server is needed to control the sharing of these resources. This document
introduces the operation of the VGA arbiter implemented for Linux kernel.

a4f3d55cb0 backlight: Add WM831x backlight driver
The WM831x series of PMICs provide DC-DC boost convertors and current
sinks which can be used together to drive LEDs for use as backlights.
Expose this functionality via the backlight API.

Since when used in this configuration the current sink and boost
convertor are very tightly coupled with a multi-stage startup for
the current sink which overlaps with the boost convertor startup
this driver bypasses the regulator API. Machine inititialisation
is responsible for ensuring that the regulators are not accessed
via both APIs.

to support Runtime PM. The driver is using the functions

 - pm_runtime_get_sync()
 - pm_runtime_put_sync()

to inform the bus code if the hardware is idle or not. If the
hardware is idle then the bus code may call the runtime dev_pm_ops
callbacks to save and restore state. pm_runtime_resume() is used
to allow the driver to access the hardware from probe().

0035fe00f7 fbcon: don't use vc_resize() on initialization
Catalin and kmemleak spotted a leak of a VC screen buffer in
vc_allocate() due to the following chain of events:

	vc_allocate()
	  visual_init(init=1)
	    vc->vc_sw->con_init(init=1)
              fbcon_init()
	        vc_resize()
	          vc->screen_buf = kmalloc()
	  vc->screen_buf = kmalloc()

The common way for the VC drivers is to set the screen dimension
parameters manually in the init case and only call vc_resize() for
!init - which allocates a screen buffer according to the new
dimensions.

fbcon instead would do vc_resize() unconditionally and afterwards set
the dimensions manually (again) for !init - i.e. completely upside
down.  The vc_resize() allocated buffer would then get lost by
vc_allocate() allocating a fresh one.

Use vc_resize() only for actual resizing to close the leak.

Set the dimensions manually only in initialization mode to remove the
redundant setting in resize mode.

changing these vars as they are only read once and removing now

used and afterwards unloading it results in:

This is caused by the current code changing the pointers assigned by
module_param.  During unload it tries to free the memory the pointers
point at which is now part of an internal structure.

The patch simply avoids changing the pointers.  This is okay as they are
read only once during the initialization process.

93274e4d4e fbcon: fix rotate upside down crash
Fix the rotate_ud() function not to crash in case of a font which has not
a width of multiple by 8: The inner loop of the font pixel copy should not
access a bit outside the font memory area.  Subtract the shift offset from
the font width will prevent this.

3730793d45 fbmon: work around compiler bug in gcc-2.4.2
There's some odd bug in gcc-4.2 where it miscompiles a simple loop whent
he loop counter is of type 'unsigned char' and it should count to 128.

The compiler will incorrectly decide that a trivial loop like this:

	unsigned char i, ...

	for (i = 0; i < 128; i++) {
		..

is endless, and will compile it to a single instruction that just
branches to itself.

This was triggered by the addition of '-fno-strict-overflow', and we
could play games with compiler versions and go back to '-fwrapv'
instead, but the trivial way to avoid it is to just make the loop
induction variable be an 'int' instead.

Thanks to Krzysztof Oledzki for reporting and testing and to Troy Moure
for digging through assembler differences and finding it.

0741241c6b connector: make callback argument type explicit
The connector documentation states that the argument to the callback
function is always a pointer to a struct cn_msg, but rather than encode it
in the API itself, it uses a void pointer everywhere.  This doesn't make
much sense to encode the pointer in documentation as it prevents proper C
type checking from occurring and can easily allow people to use the wrong
pointer type.  So convert the argument type to an explicit struct cn_msg
pointer.

This deifdefs the driver and adds an explicit HAVE_CLK dependency. Given
that all SH platforms provide it, there is no reason to keep this as an

already, so adding this as an additional dependency is not terribly

600ce1a0fa drivers/video/s3c-fb.c: fix clock setting for Samsung SoC Framebuffer
Correct the CLKVAL_F field value of VIDEO MAIN CONTROLLER 0 REGITSTER.

Frame Rate is 1 / [ { (VSPW+1) + (VBPD+1) + (LIINEVAL + 1) + (VFPD+1)
} x {(HSPW+1) + (HBPD +1)
+ (HFPD+1) + (HOZVAL + 1) } x { ( CLKVAL+1 ) / ( Frequency of Clock
source ) } ] and VCLK = Video Clock Source / (CLKVAL +1).

therefore CLKVAL_F should be "CLKVAL_F = Frequency of Clock source / pixel
clock * refresh".

for this, I added refresh value in platform data like below.

static struct s3c_fb_pd_win xxx_fb_win0 = {
	/* this is to ensure we use win0 */
	.win_mode = {
		.refresh	= 60,
		.pixclock	= (66+4+2+480)*(15+5+3+800),
		.left_margin	= 66,
		.right_margin	= 2,
		.upper_margin	= 15,
		.lower_margin	= 3,
		.hsync_len	= 4,
		.vsync_len	= 5,
		.xres		= 480,
		.yres		= 800,
	},
	.max_bpp	= 32,
	.default_bpp	= 24,
};

static struct s3c_fb_platdata xxx_lcd_pdata __initdata = {
	.win[0]		= &xxx_fb_win0,
	.vidcon0	= VIDCON0_VIDOUT_RGB | VIDCON0_PNRMODE_RGB,
	.vidcon1	= VIDCON1_INV_HSYNC | VIDCON1_INV_VSYNC
			| VIDCON1_INV_VCLK | VIDCON1_INV_VDEN,
	.setup_gpio	= s5pc1xx_fb_gpio_setup_24bpp,
};

xxx_machine_init()
{
                   .
                   .
                   .
               s3c_fb_set_platdata(&xxx_lcd_pdata);
}

platform data defined in machine code should be setting using
s3c_fb_set_platdata().

Commit 537a1bf059 (fbdev: add mutex for
fb_mmap locking) introduces a ->mm_lock mutex for protecting smem
assignments. Unfortunately in the case of sm501fb these happen quite
early in the initialization code, well before the mutex_init() that takes
place in register_framebuffer(), leading to:

   Badness at kernel/mutex.c:207

   Pid : 1, Comm:          swapper
   CPU : 0                 Not tainted  (2.6.31-rc1-00284-g529ba0d-dirty #2273)

   PC is at __mutex_lock_slowpath+0x72/0x1bc
   PR is at __mutex_lock_slowpath+0x66/0x1bc
   ...

matroxfb appears to have the same issue and has solved it with an early
mutex_init(), so we do the same for sm501fb.

82e8b54229 backlight: fix pwm_bl.c to notify platform code when suspending
When suspending, pwm-bl sets duty cycle to 0, and shuts down the pwm
device.

This patch ensure that the platform code is called before that
(through the notify callback_, leaving a chance for the platform code
to configure GPIOs (shutting off the backlight, for example), much like
it is done during normal operations.

537a1bf059 fbdev: add mutex for fb_mmap locking
Add a mutex to avoid a circular locking problem between the mm layer
semaphore and fbdev ioctl mutex through the fb_mmap() call.

Also, add mutex to all places where smem_start and smem_len fields change
so the mutex inside the fb_mmap() is actually used.  Changing of these
fields before calling the framebuffer_register() are not mutexed.

This is 2.6.31 material.  It removes one lockdep (fb_mmap() and
register_framebuffer()) but there is still another one (fb_release() and
register_framebuffer()).  It also cleans up handling of the smem_start and
smem_len fields used by mutexed section of the fb_mmap().

Here are the at91 specific files dedicated to the at91sam9g45 series. They
mimic the traditional at91 way of managing chips & boards.

The first board that embeds at91sam9g45 chip is the AT91SAM9G45-EKES. In
the future, the main board for this 9g45 series will be the
AT91SAM9M10G45-EK (I choose this last name for the board file).

Simple drivers are enabled in _devices and board- files. Newer peripheral
support will be added in future patches.

Incuded peripherals support (for now):
- USART
- SPI
- Ethernet
- NAND flash
- LCD
- gpio/joystick/buttons
- leds and pwm

4410f39109 fbdev: add support for handoff from firmware to hw framebuffers
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.

39000d654c Samsung SoC Framebuffer driver: add Alpha Channel support
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.

97b9a5a28b atmel-lcdc: fix pixclock upper bound detection
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.

James' ack dates back to the previous submission (way to long ago), when the

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.

fa1b2ca4fa i2c: Do not probe for TV chips on Voodoo3 adapters
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.
