This patch adds waveform storing capability to broadsheetfb. It uses the
firmware class to retrieve the waveform, and the request to initiate the
waveform storing is done via a driver sysfs entry, loadstore_waveform.
Broadsheet is a framebuffer device. It is slightly different from a
typical framebuffer controller that drives a normal TFT-LCD display. Most
E-Ink display panels require a waveform in order to function. That is, in
order to drive the state of a pixel to black, gray, or white, a specific
waveform is utilized. Basically, that waveform represents the specific
E-field wiggling needed to get the pixel to its optimal state given
current temperature, and its previous state. TN/IPS-LCDs use a similar
concept but the driving waveform is sufficiently simple that it is
internalized in the TFT source/gate driver.
These E-Ink waveforms are specific to a production batch. That is, a
batch of display films are produced, then they get characterized and a
waveform is generated for that batch. Broadsheet, typically, is attached
to its private SPI flash which is then flashed with this waveform.
Users won't be able to see the waveform and typically won't ever need to
know about it. If however, the display panel attached to broadsheet is
changed out, then they will need to update their waveform. That would
typically be done at a factory or repair facility rather than by a user.

Add support for the color depth 15 on IGA1 and 30 on IGA1 and IGA2. To
allow the usage of those the driver now refuses color depth that are
totally off and otherwise the selection in viafb_check_var is used.
Therefore the first call to this for the first framebuffer was delayed a
bit. It only enables the new formats if they are requested exactly
(viafb_bpp=15|30).
As this is a new feature, no regressions are expected. The color depth 15
was successfully tested. Didn't get anything usable for 30 but that might
be the programs fault. I would like to get some feedback whether it works
as expected or not if somebody knows a program/configuration where it
should.

This is a rewritten version of viafb_setcolreg. The hardware register
writes were split up and moved to hw.c where they belong as this is really
low level stuff. It was made dual fb aware.
Furthermore viafb_setcmap was removed as the problem with 8bpp originated
from a bug in writing multiple color registers at once. The removal of
viafb_setcmap might introduce a small performance regression but its
certainly better to receive the correct result a bit slower than a garbled
picture fast. It should give us a working 8bpp mode and is more
extensible than the old hardcoded code. No other regressions are expected
but as the hardware might be a bit picky it might cause some regressions
in 8bpp mode on some hardware although I doubt that.

Make color checking a bit more tolerant in what values it allows and more
fine grained to later support 15 and 30 bits formats. It splits the
filling of the color information in var to a seperate function and sets
some color related values in var that where previously untouched.
This could be a bug fix but at least I don't know any applications that
was fooled by not correctly setting the fields in var. At least no

Some code depended on IGA1_IGA2 which was never set (at least with the
symbolic name). Remove this dead code although it might one day be useful
to get a hint on how some things might work. However as this is dead it
is likely full of bugs and would prevent a clean structure (as it has some
very strange things).
Dead code -> no regressions, at least if VIA doesn't do anything very ugly.

This patch splits color mode setting up in seperate functions. Some
hardware initialization that was previously mixed with it is moved to
viafb_setmode. As are the calls to the newly created function. This is
yet another little step towards controlling each IGA on its own.
As this patch really aims too mimic the old behaviour no regressions are
expected. However I noticed that 8bpp (or 6bpp?) seems actually a bit
broken before and after the patch.

This patch is an attempt to make viafb_set_par work correctly with more
than one framebuffer. As modesetting is not (yet/easily) possible for
each individual IGA it uses the (normally to be avoided) global variables
viafbinfo{,1} to ensure that each function is called with the correct
values.
This patch (finally) allows usable dual framebuffer setups and should not
affect non dual fb ones. It works in some (most?) configurations as
sometimes the driver still gets device connections wrong. It can be worth
to try the devices in reverse order (in viafb_active_dev).
The user experience is still not very nice as:
- on the second fb you'll normally have a garbled picture as long as
no application draws to it
goal: auto on/off devices depending on reference counting
- as the whole machinery is always done you can see mode changes also
in an unaffected framebuffer
goal: split modesetting up for each individual IGA

Set always the correct video address. Especially do panning right on
multiple IGAs.
This should have no effect on single monitor mode (no SAMM, no dual fb).
For SAMM without dual fb this might break something as I really cannot
image what we are supposed to do for different resolutions with a single
framebuffer as we can't get data out of nowhere (no, they are not set up
in something one would call "expanded"). Previously I got for that funny
colored pictures as the second IGA pointed to video memory that was never
written to. After the patch it'll work as cloning if the first and second
mode are identical (this was working already without SAMM). Finally for
dual fb this should push us a step in the right direction.

This is the first step to remove an artificial global index that was used
in two ways:
1. As a pseudo index in the mode table. Pseudo as you had to search
through the table to find the referenced entry. This was replaced by
using a pointer to the entry.
2. As a shortcut to compare a combination of horizontal and vertical
resolution at the same time.
This was replaced by a "(hres<<16) | vres" which is good enough for
now and the near future. If vres or hres become greater than 2^16 this
might indeed cause problems but this solution allows to split this
indexing mess up without the requirement to do even more code changes.
This is a big change that will allow more clean ups. It should be a bit
faster but that is probably not relevant for normal operation. No
regressions expected but as this is a relatively big step heavy testing is
appreciated.

A pointer to a probe callback is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

Benefits of this constification:
* prevents modification of data that is shared
(referenced) by many other structure instances
at runtime
* detects/prevents accidental (but not intentional)
modification attempts on archs that enforce
read-only kernel data at runtime
* potentially better optimized code as the compiler
can assume that the const data cannot be changed
* the compiler/linker move const data into .rodata
and therefore exclude them from false sharing

modes and one for gaming/on-ac applications. These GPUs are typically
wired to the laptop panel and VGA ports via a multiplexer unit which
is controlled via ACPI methods.
4 combinations of systems typically exist - with 2 ACPI methods.
Intel/ATI - Lenovo W500/T500 - use ATPX ACPI method
ATI/ATI - some ASUS - use ATPX ACPI Method
Intel/Nvidia - - use _DSM ACPI method
Nvidia/Nvidia - - use _DSM ACPI method.
TODO:
This patch adds support for the ATPX method and initial bits
for the _DSM methods that need to written by someone with
access to the hardware.
Add a proper non-debugfs interface - need to get some proper
testing first.
v2: add power up/down support for both devices
on W500 puts i915/radeon into D3 and cuts power to radeon.
v3: redo probing methods, no DMI list, drm devices call to
register with switcheroo, it tries to find an ATPX method on
any device and once there is two devices + ATPX it inits the
switcher.
v4: ATPX msg handling using buffers - should work on more machines
v5: rearchitect after more mjg59 discussion - move ATPX handling to
radeon driver.
v6: add file headers + initial nouveau bits (to be filled out).
v7: merge delayed switcher code.
v8: avoid suspend/resume of gpu that is off
v9: rearchitect - mjg59 is always right. - move all ATPX code to
radeon, should allow simpler DSM also proper ATRM handling
v10: add ATRM support for radeon BIOS, add mutex to lock vgasr_priv
v11: fix bug in resuming Intel for 2nd time.
v12: start fixing up nvidia code blindly.
v13: blindly guess at finishing nvidia code
v14: remove radeon audio hacks - fix up intel resume more like upstream
v15: clean up printks + remove unnecessary igd/dis pointers
mount debugfs
/sys/kernel/debug/vgaswitcheroo/switch - should exist if ATPX detected
+ 2 cards.
DIS - immediate change to discrete
IGD - immediate change to IGD
DDIS - delayed change to discrete
DIGD - delayed change to IGD
ON - turn on not in use
OFF - turn off not in use
Tested on W500 (Intel/ATI) and T500 (Intel/ATI)

The valkyriefb driver assumes that this logic holds:
mac_vmode_to_var(X, cmode, &var);
mac_var_to_vmode(&var, &vmode, &cmode);
assert(vmode == X);
But it doesn't hold because mac_var_to_vmode() can return a mode with a
slower pixel clock, even when a match is available. So we end up with this
failure:
using video mode 11 and color mode 0.
valkyriefb: vmode 12 not valid.
valkyriefb: can't set default video mode
valkyriefb: vmode 12 not valid.
Rather than have mac_var_to_mode() return the first reasonable mode it
finds, have it return the mode that is closest to the requested one (or
the mode with the closest longer pixel clock period if there is no exact
match).

Both the store queue API and the PMB remapping take unsigned long for
their pgprot flags, which cuts off the extended protection bits. In the
case of the PMB this isn't really a problem since the cache attribute
bits that we care about are all in the lower 32-bits, but we do it just
to be safe. The store queue remapping on the other hand depends on the
extended prot bits for enabling userspace access to the mappings.

Instead of configuring only VC0 to be usable, configure all four VCs
similarly. This is needed to utilize the other VCs.
Setting the FIFO sizes evenly for all VCs, regardless of how many VCs are
actually used, is not optimal. However, this affects only cases when
larger amounts of data are written or read via L4, meaning that normal use
cases are not affected.
At some point this could be optimized better to suit different use cases.

It looks like on OMAP3 some DSS pins need VDDS_DSI to function properly.
This has not been confirmed from TI, but looking at figure 15-1 "Display
subsystem highlight" from the TRM, some data pins come near the DSI and SDI
blocks. This is not very hard evidence, but the fact remains that with the
power on, pixels are ok, and with the power off, pixels are not ok.
It may also be that VDDS_SDI is needed to power some pins, but as normally
both VDDS_SDI and VDDS_DSI come from the same power source, this hasn't
been shown.
It seems that a single driver can only get a regulator once. This patch
solves it by getting all the required regulators in one place, and from
which the submodules then get the regulators they need.

Support for RGB444 (12-bit) pixel format has been introduced into omapfb/lcdc
by Mark Underwood on 2006-05-26 (commit
f74edb6668aad9fc8e81585861b18f996c78a574) in preparation for Amstrad Delta
(E3) videophone LCD display support.
Before the Amstrad Delta LCD patch by Jonathan McDowell was applied (on
2006-08-04, commit 8d22fb2ea004cdb6379b54c1a8fd1546cfe40ed7), omapfb and lcdc
code was changed substantially (commit
e563dc81aa01bd8bbb01bc53975a15c398715f62 dated 2006-06-26) in a way that broke
Mark's 12-bit display support. Than, a patch by Jonathan, that supposed to
correct the problem, was introduced immediatelly (on 2006-08-04, commit
e10a75b49e7a57ae17c28b705153c70eba15a8ef).
As a result, the Amstrad Delta display was working correctly at boot time,
with fbset reporting:
geometry 480 320 480 320 16
...
rgba 4/8,4/4,4/0,0/0
However, after first framebuffer reinitialization, colors were no longer being
displayed correctly and fbset was reporting:
rgba 5/11,6/5,5/0,0/0
The patch tries to correct the issue by setting plane->color_mode depending on
panel->bpp, not var->bits_per_pixel.
Created and tested on Amstrad Delta against linux-2.6.33-rc3.

In struct device_node, the phandle is named 'linux_phandle' for PowerPC
and MicroBlaze, and 'node' for SPARC. There is no good reason for the
difference, it is just an artifact of the code diverging over a couple
of years. This patch renames both to simply .phandle.
Note: the .node also existed in PowerPC/MicroBlaze, but the only user
seems to be arch/powerpc/platforms/powermac/pfunc_core.c. It doesn't
look like the assignment between .linux_phandle and .node is
significantly different enough to warrant the separate code paths
unless ibm,phandle properties actually appear in Apple device trees.
I think it is safe to eliminate the old .node property and use
phandle everywhere.

Fix divide by zero and broken output. Commit 600ce1a0fa ("fix clock
setting for Samsung SoC Framebuffer") introduced a mandatory refresh
parameter to the platform data for the S3C framebuffer but did not
introduce any validation code, causing existing platforms (none of which
have refresh set) to divide by zero whenever the framebuffer is
configured, generating warnings and unusable output.
Ben Dooks noted several problems with the patch:
- The platform data supplies the pixclk directly and should already
have taken care of the refresh rate.
- The addition of a window ID parameter doesn't help since only the
root framebuffer can control the pixclk.
- pixclk is specified in picoseconds (rather than Hz) as the patch
assumed.
and suggests reverting the commit so do that. Without fixing this no
mainline user of the driver will produce output.

The intelfb driver sets color map depending on currently active pipe.
However, if an LVDS display is attached (like in laptop) the active pipe
variable is never set. The default value is PIPE_A and can be wrong. Set
up the pipe variable during driver initialization after hardware state was
read.
Also, the detection of the active display (and hence the pipe) is wrong.
The pipes are assigned to so called planes. Both pipes are always enabled
on my laptop but only one plane is enabled (the plane A for the CRT or the
plane B for the LVDS). Change active pipe detection code to take into
account a status of the plane assigned to each pipe.
The problem is visible in the 8 bpp mode if colors above 15 are used. The
first 16 color entries are displayed correctly.

Also, while at it, if we see (*str && isspace(*str)), we can be sure to
remove the first condition (*str) as the second one (isspace(*str)) also
evaluates to 0 whenever *str == 0, making it redundant. In other words,
"a char equals zero is never a space".
