Allocate the framebuffer memory as coherent, otherwise the framebuffer
will suffer from artifacts when displaying scrolling text or video.
This can be replicated on i.MX6SX (armv7), which has more complex memory
architecture compared to the i.MX23/28 (armv5).

%ul was probably meant as %lu since the former would print
an unsigned value and a letter l.
But in fact the whole value we are printing in u32 anyway, so
we don't need the format to be long. Therefore just drop the l
altogether.

The amba-clcd-versatile.c code is always built-in and has to
be done that way because it gets called by platform code that is
also built-in. However, it now also gets called from the
core CLCD driver through the .init_panel callback function,
which leads to a build error when the framebuffer is configured
as a loadable module:
ERROR: "versatile_clcd_init_panel" [drivers/video/fbdev/amba-clcd-mod.ko] undefined!
The same thing happens for the nomadik driver, although that
could be linked into the core module if we want to:
ERROR: "nomadik_clcd_init_panel" [drivers/video/fbdev/amba-clcd.ko] undefined!
ERROR: "nomadik_clcd_init_board" [drivers/video/fbdev/amba-clcd.ko] undefined!
For consistency, I'm taking the same approach in both cases here
and just export the functions to make them usable by the driver.
Alternatively, we could split out the CONFIG_OF-code from amba-clcd-versatile.c
into a new file and link those two together with the core driver as one
module.

We need to mask all registers of the Integrator/CP core module

The addition of the Nomadik support in this driver introduced
a bug in clcdfb_of_init_display(), which now calls init_panel
with an uninitialized 'endpoint' pointer, as "gcc -Wmaybe-uninitialized"
warns:
drivers/video/fbdev/amba-clcd.c: In function 'clcdfb_of_init_display':
drivers/video/fbdev/amba-clcd.c:785:5: error: 'endpoint' may be used uninitialized in this function [-Werror=maybe-uninitialized]
This reverts the broken part of the function to what it was before
the patch, which is the best guess I have to what it should be.
I assume this was left over from an attempted rework of the
code that was partially backed out.

When using efifb with a 16-bit (5:6:5) visual, fbcon's text is rendered
in the wrong colors - e.g. text gray (#aaaaaa) is rendered as green
(#50bc50) and neighboring pixels have slightly different values
(such as #50bc78).
The reason is that fbcon loads its 16 color palette through
efifb_setcolreg(), which in turn calculates a 32-bit value to write
into memory for each palette index.
Until now, this code could only handle 8-bit visuals and didn't mask
overlapping values when ORing them.
With this patch, fbcon displays the correct colors when a qemu VM is
booted in 16-bit mode (in GRUB: "set gfxpayload=800x600x16").

The workqueue "esd_wq" has only a single workitem(&md->esd_work)
and hence doesn't require ordering. Also, it is not being used on a
memory reclaim path. Hence, the singlethreaded workqueue has been
replaced with the use of system_wq.
System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.

clock when ARM clock frequency changes (ratio between frequencies of
ARM's parent clock (fclk) and clock for peripherals remains fixed).
This is needed only on S3C24xx platform when cpufreq driver is enabled
so limit the ifdef to respective cpufreq Kconfig.

This adds a special panel init hook for the ARM reference designs
Integrator (IM-PD1), Versatile and RealView, so we can configure
a DPI panel from device tree and have it working without
boardfiles for these machines.
Basically this is the same code as from the board files, just
moved over to look up the syscon DT node and manipulate the
special CLCD register from their regmap.
Tested on RealView PB11MPcore.

In the .board_init() callback will set up a mux register in
the Nomadik system controller. It so happens that the platform
has two display output engines, and we have to poke a bit in
a special register to make sure the right engine is muxed in
as they are mutually exclusive.
The Nomadik CLCD variant is instantiated on a platform where
it is combined with a 800x480 TPO WVGA display. In the
.panel_init() hook we will detect this display from the
compatible string and set it up. We also add .enable() and
.disable() callbacks for it as the sleep state is software
controlled.
The display is connected with a special 3-wire serial bus
(this is sadly neither I2C or SPI) using three GPIO lines that
we bitbang to detect the display and enable/disable sleep
state.

The Nomadik variant has a few special quirks that need to be respected
to make the driver work:
- The block need to be clocked during writing of the TIMn registers
or the bus will stall.
- Special bits in the control register select how many of the output
display lines get activated.
- Special bits in the control register select how to manage the
different 565 and 5551 modes.
- There is a packed 24bit graphics mode, i.e 888 pixels can be stored
in memory is three consecutive bytes, not evenly aligned to a 32bit
word.
This patch uses the vendor data pointer from the AMBA matching mechanism
to track the quirks for this variant, and adds two hooks that variants
can use to initialize boards and panels during start-up. These will
later be used to adopt a Nomadik board profile.

There are CLCDs connected with the pads in BGR rather than RGB
order. It really doesn't matter since the CLCD has a flag and
a bit to switch the position of the RGB and BGR components.
This is needed to put something logical into the
arm,pl11x,tft-r0g0b0-pads property of the device tree on the
Nomadik which will then be <16 8 0>.

The device tree bindings from display-timing.txt allows us to
specify if data enable, hsync, vsync or the pixed clock should be
inverted on the way to the display. The driver does not currently
handle this so add support for those flags as it is needed for
the Versatile Sanyo LCD display.
Note that the previous behaviour was to invert the pixel clock
for all displays, so unless the pixel clock polarity is
explicitly defined in the device tree (i.e. the timings node
has the "pixelclk-active" property) we fall back to inverting
the pixel clock. This needs some extra compatibility code.
Since the timing flags have to be set up inside the struct
clcd_panel, we need to refactor the code a bit to pass around
the panel rather than just the mode.

If the device is probed from device tree, we can support
backlight. This is used with some systems such as the
ST Microelectronics Nomadik.
We have to add HAS_IOMEM to the dependencies of CLCD since
the backlight class device will now be selected, and if it
gets selected on an arch that does not have IOMEM,
compilation will fail.

The voltage changing code in this driver is broken and should be
removed. The driver sets a single, exact voltage on probe. Unless
there is a very good reason for this (which should be documented in
comments) constraints like this need to be set via the machine
constraints, voltage setting in a driver is expected to be used in cases
where the voltage varies at runtime.
In addition client drivers should almost never be calling
regulator_can_set_voltage(), if the device needs to set a voltage it
needs to set the voltage and the regulator core will handle the case
where the regulator is fixed voltage. If the driver can skip setting
the voltage it should just never set the voltage.

The dma-mapping core and the implementations do not change the DMA
attributes passed by pointer. Thus the pointer can point to const data.
However the attributes do not have to be a bitfield. Instead unsigned
long will do fine:
1. This is just simpler. Both in terms of reading the code and setting
attributes. Instead of initializing local attributes on the stack
and passing pointer to it to dma_set_attr(), just set the bits.
2. It brings safeness and checking for const correctness because the
attributes are passed by value.

When building with "make W=1", we get a warning about an empty stub
function that does nothing but reassign its one of its arguments:
drivers/video/fbdev/core/fbmon.c: In function 'fb_edid_to_monspecs':
drivers/video/fbdev/core/fbmon.c:1497:67: error: parameter 'specs' set but not used [-Werror=unused-but-set-parameter]
We can simply make that function completely empty to avoid the warning.
This prevents a warning which everyone will see after "CFLAGS: add
-Wunused-but-set-parameter" is merged.

smallest supported chip
This patch changes the compatibility string to match with the smallest
supported chip (EP7209). Since the DT-support for this CPU is not yet
announced, this change is safe.

The LP8556 datasheet describes an EN/VDDIO input, which serves "both as
a chip enable and as a power supply reference for PWM, SDA, and SCL
inputs." The LP8556 that I'm testing doesn't respond properly if I try
to talk I2C to it too quickly after enabling VDDIO, and the LP8555
datasheet mentions a t_RESPONSE delay of up to 1 millisecond.
Support this EN/VDDIO by adding a regulator property to the binding;
enabling this regulator at probe time; and sleeping for 1 to 2ms, if the
EN/VDDIO regulator was provided.

Namely convert:
* IS_FG -> con_is_fg
* DO_UPDATE -> con_should_update
* CON_IS_VISIBLE -> con_is_visible
DO_UPDATE was a weird name for a yes/no answer, so the new name is
con_should_update.

Merge omapdss public header refactoring, which separates the public
header into omapdrm and omapfb parts.
|
|
Merge omapdrm PLL work, which makes it possible to use the DSS PLLs in a
versatile manner, for example, HDMI PLL can be used for LCDs.
|
|
Copy the content of video/omapdss.h to a new (video/omapfb_dss.h) header
file and convert the omapfb drivers to use this new file.
The new header file is needed to complete the separation of omapdrm and
omapfb implementation of DSS.

In legacy mode (non DT mode) support only composite connector type. The
only user for this is rx51, using composite type.
Dropping the connector_type selection via pdata will allow cleanups in
omapdss (drm vs fbdev).
