Stefan Kristiansson e61d05dd88 video: add OpenCores VGA/LCD framebuffer driver
This adds support for the VGA/LCD core available from OpenCores:
http://opencores.org/project,vga_lcd

The driver have been tested together with both OpenRISC and
ARM (socfpga) processors.

Stephen Warren 26549c8d36 drivers/video: implement a simple framebuffer driver
A simple frame-buffer describes a raw memory region that may be rendered
to, with the assumption that the display hardware has already been set
up to scan out from that buffer.

This is useful in cases where a bootloader exists and has set up the
display hardware, but a Linux driver doesn't yet exist for the display
hardware.

Examples use-cases include:

* The built-in LCD panels on the Samsung ARM chromebook, and Tegra
  devices, and likely many other ARM or embedded systems.  These cannot
  yet be supported using a full graphics driver, since the panel control
  should be provided by the CDF (Common Display Framework), which has been
  stuck in design/review for quite some time.  One could support these
  panels using custom SoC-specific code, but there is a desire to use
  common infra-structure rather than having each SoC vendor invent their
  own code, hence the desire to wait for CDF.

* Hardware for which a full graphics driver is not yet available, and
  the path to obtain one upstream isn't yet clear.  For example, the
  Raspberry Pi.

* Any hardware in early stages of upstreaming, before a full graphics
  driver has been tackled.  This driver can provide a graphical boot
  console (even full X support) much earlier in the upstreaming process,
  thus making new SoC or board support more generally useful earlier.

Tomi Valkeinen a38884f681 videomode: simplify videomode Kconfig and Makefile
This patch simplifies videomode related Kconfig and Makefile. After this
patch, there's only one non-user selectable Kconfig option left,
VIDEOMODE_HELPERS. The reasons for the change:

* Videomode helper functions are not something that should be shown in
  the kernel configuration options. The related code should just be
  included if it's needed, i.e. selected by drivers using videomode.

* There's no need to have separate Kconfig options for videomode and
  display_timing. First of all, the amount of code for both is quite
  small. Second, videomode depends on display_timing, and display_timing
  in itself is not really useful, so both would be included in any case.

* CONFIG_VIDEOMODE is a bit vague name, and CONFIG_VIDEOMODE_HELPERS
  describes better what's included.

Zhou Zhu 59393bb94c video: mmp display subsystem
Add mmp display subsystem to support Marvell MMP display controllers.

This subsystem contains 4 parts:
--fb folder
--core.c
--hw folder
--panel folder

1. fb folder contains implementation of fb.  fb get path and overlay
   from common interface and operates on these structures.

2. core.c provides common interface for a hardware abstraction.  Major
   parts of this interface are:

   a) Path: path is a output device connected to a panel or HDMI TV.  Main
      operations of the path is set/get timing/output color.  fb operates
      output device through path structure.

   b) Ovly: Ovly is a buffer shown on the path.

      Ovly describes frame buffer and its source/destination size, offset,
      input color, buffer address, z-order, and so on.  Each fb device maps
      to one overlay.

3. hw folder contains implementation of hardware operations defined by
   core.c.  It registers paths for fb use.

4. panel folder contains implementation of panels.  It's connected to
   path.  Panel drivers would also regiester panels and linked to path
   when probe.

Arve Hjønnevåg c289ba2d26 goldfish: framebuffer driver
Framebuffer support for the Goldfish emulator.  This takes the Google
emulator and applies the x86 cleanups as well as moving the blank
methods to the usual Linux place and dropping the Android early suspend
logic (for now at least, that can be looked at as Android and upstream
converge).  Dropped various oddities like setting MTRRs on a virtual
frame buffer emulation...

With the drivers so far you can now boot a Linux initrd and have fun.

Steffen Trumtrar cc3f414cf2 video: add of helper for display timings/videomode
This adds support for reading display timings from DT into a struct
display_timings. The of_display_timing implementation supports multiple
subnodes. All children are read into an array, that can be queried.

If no native mode is specified, the first subnode will be used.

For cases where the graphics driver knows there can be only one
mode description or where the driver only supports one mode, a helper
function of_get_videomode is added, that gets a struct videomode from DT.

Steffen Trumtrar 8714c0cecf video: add display_timing and videomode
Add display_timing structure and the according helper functions. This allows
the description of a display via its supported timing parameters.

Also, add helper functions to convert from display timings to a generic videomode
structure.

The struct display_timing specifies all needed parameters to describe the signal
properties of a display in one mode. This includes
    - ranges for signals that may have min-, max- and typical values
    - single integers for signals that can be on, off or are ignored
    - booleans for signals that are either on or off

As a display may support multiple modes like this, a struct display_timings is
added, that holds all given struct display_timing pointers and declares the
native mode of the display.

Although a display may state that a signal can be in a range, it is driven with
fixed values that indicate a videomode. Therefore graphic drivers don't need all
the information of struct display_timing, but would generate a videomode from
the given set of supported signal timings and work with that.

The video subsystems all define their own structs that describe a mode and work
with that (e.g. fb_videomode or drm_display_mode). To slowly replace all those
various structures and allow code reuse across those subsystems, add struct
videomode as a generic description.

This patch only includes the most basic fields in struct videomode. All missing
fields that are needed to have a really generic video mode description can be
added at a later stage.

Sascha Hauer f0a523b5e5 video: Add i.MX23/28 framebuffer driver
changes since v2:

- use v3 and v4 for specifying the ip version instead of i.MX23/28.
  This is a better namespace when future versions are added.
- rename mach/fb.h to mach/mxsfb.h

changes since v1:
- Add a LCDC_ prefix to the register names.
- use set/clear registers where appropriate
- protect call to mxsfb_disable_controller() in mxsfb_remove()
  with a (host->enabled) as suggested by Lothar Wassmann

Daniel Mack 364dbdf3b6 video: add driver for PXA3xx 2D graphics accelerator
This adds a driver for the the 2D graphics accelerator found on PXA3xx
processors. Only resource mapping, interrupt handling and a simple ioctl
handler is done by the kernel part, the rest of the logic is implemented
in DirectFB userspace.

Graphic applications greatly benefit for line drawing, blend, and
rectangle and triangle filling operations.

Benchmarks done on a PXA303 using the df_dok benchmarking tool follow,
where the value in square brackets show the CPU usage during that test.

Without accelerator (benchmarking 256x252 on 480x262 RGB16 (16bit)):

to a real driver.

The outstanding cleanups are all minor, with some of them dependent on

Tomi Valkeinen afedec183e OMAP: Add VRAM manager
Add a Video RAM manager for OMAP 2 and 3 platforms. VRAM manager is used
to allocate large continuous blocks of SDRAM or SRAM. The features VRAM
manager has that are missing from dma_alloc_* functions are:

- Support for OMAP2's SRAM
- Allocate without ioremapping
- Allocate at defined physical addresses
- Allows larger VRAM area and larger allocations

The upcoming DSS2 uses VRAM manager.

VRAM area size can be defined in kernel config, board file or with
kernel boot parameters. Board file definition overrides kernel config,
and boot parameter overrides kernel config and board file.

Sudhakar Rajashekhara 4ed824d9ae davinci: fb: Frame Buffer driver for TI DA8xx/OMAP-L1xx
Add LCD controller (LCDC) driver for TI's DA8xx/OMAP-L1xx architecture.
LCDC specifications can be found at http://www.ti.com/litv/pdf/sprufm0a.

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:
