Adds different wiring mode for the LCD screen.
The legacy atmel LCDC IP uses a non standard color mode, "BGR-555.1" instead
"RGB-565". The major part of graphic stacks for embedded systems uses only
"RGB-565". It is possible to swap LCD IOs instead of doing this bit swapping
by software (See application note AT91SAM9 LCD Controller
http://www.atmel.com/dyn/resources/prod_documents/doc6300.pdf)This wire swapping is done on the at91sam9rl-ek board (board code
using this patch will come later).Signed-off-by: Nicolas Ferre

Teach atmel_lcdfb driver how to suspend/resume.
Note that the backlight control should probably do more of the same stuff:
turning off display power (more than just the backlight) and stopping the
clocks (and dma to drive the no-longer-seen display). No point in wasting
power to generate images that can't be observed, after all...Signed-off-by: David Brownell

On the sam9 EK boards, the LCD backlight is hooked up to a PWM output from
the LCD controller. It's controlled by "contrast" registers though.This patch lets boards declare that they have that kind of backlight
control. The driver can then export this control, letting screenblank and
other operations actually take effect ... reducing the typically
substantial power drain from the backlight.Note that it's not fully cooked
- doesn't force backlight off during system suspend
- the "power" and "blank" events may not be done right
This should be easily added in the future.[nicolas.ferre@atmel.com: remove unneeded inline and rename functions]

Setting a display timing parameter too high or too low may cause it to
wrap around and thus become completely wrong. Validate the timings in
atmel_lcdfb_check_var() and saturate to the highest or lowest possible
value if necessary.Signed-off-by: Haavard Skinnemoen

To actually write a bootloader (or, say, the lguest launcher)
currently requires duplication of these structures. Making them
includable from userspace is much nicer.We merge the common userspace-required definitions of e820_32/64.h
into e820.h for export.Signed-off-by: Rusty Russell

This contains the following changes:
* Overlay surface alpha is configured separately from the overlay. This
prevents display glitches (configure and fill the overlay first, set
alpha to a visible value next)* Added an ioctl for configuring transparency of the Overlay and graphics
planes. Blend mode, colorkey mode and global alpha mode are supported.* Added an ioctl for setting the plane order. The overlay plance can be placed
over or
under the graphics plane.* Added an ioctl for setting and reading chip registers, with mask.
* Updated copyright for 2007

uvesafb is an enhanced version of vesafb. It uses a userspace helper (v86d)
to execute calls to the x86 Video BIOS functions. The driver is not limited
to any specific arch and whether it works on a given arch or not depends on
that arch being supported by the userspace daemon. It has been tested on
x86_32 and x86_64.A single BIOS call is represented by an instance of the uvesafb_ktask
structure. This structure contains a buffer, a completion struct and a
uvesafb_task substructure, containing the values of the x86 registers, a flags
field and a field indicating the length of the buffer. Whenever a BIOS call
is made in the driver, uvesafb_exec() builds a message using the uvesafb_task
substructure and the contents of the buffer. This message is then assigned a
random ack number and sent to the userspace daemon using the connector
interface.The message's sequence number is used as an index for the uvfb_tasks array,
which provides a mapping from the messages coming from userspace to the
in-kernel uvesafb_ktask structs.The userspace daemon performs the requested operation and sends a reply in the
form of a uvesafb_task struct and, optionally, a buffer. The seq and ack
numbers in the reply should be exactly the same as those in the request.Each message from userspace is processed by uvesafb_cn_callback() and after
passing a few sanity checks leads to the completion of a BIOS call request.Signed-off-by: Michal Januszewski

bits have been added to support this chip as well.Signed-off-by: Maciej W. Rozycki

This patch adds a way to create and use the video plane (YUV overlay) and
scaling video scaling features of the chip.The overlay is configured, resized and modified using a device specific
ioctl.Also included in this patch:
- If no platform data was passed, print an error and exit instead of crashing.
- Added a write_reg(_dly) macro. This improves readability when
manipulating chip registers. (no more udelay() after each write).
- Comments about some issues.Signed-off-by: Raphael Assenat
