67cf9c0a00 ARM: at91: fix LCD-wiring mode
Fix regression introduced by commit 787f9fd232 ("atmel_lcdfb: support
16bit BGR:565 mode, remove unsupported 15bit modes") which broke 16-bpp
modes for older SOCs which use IBGR:555 (msb is intensity) rather than
BGR:565.

The above commit removes the RGB:555-wiring hack by
removing the no longer used ATMEL_LCDC_WIRING_RGB555 define.

Fix regression introduced by commit 787f9fd232 ("atmel_lcdfb: support

Use SOC-type to determine the pixel layout.

Tested on at91sam9263 and at91sam9g45.

Merge tag 'disintegrate-fbdev-20121220' of git://git.infradead.org/users/dhowells/linux-headers

Pull fbdev UAPI disintegration from David Howells:
 "You'll be glad to here that the end is nigh for the UAPI patches.
  Only the fbdev/framebuffer piece remains now that the SCSI stuff has
  gone in.

  Here are the UAPI disintegration bits for the fbdev drivers.  It
  appears that Florian hasn't had time to deal with my patch, but back
  in December he did say he didn't mind if I pushed it forward."

Yay.  No more uapi movement.  And hopefully no more big header file
cleanups coming up either, it just tends to be very painful.

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.

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.

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.

ca2e16faa7 OMAP: board-files: fix i2c_bus for tfp410
The i2c handling in tfp410 driver, which handles converting parallel RGB
to DVI, was changed in 958f2717b8
(OMAPDSS: TFP410: pdata rewrite). The patch changed what value the
driver considers as invalid/undefined.  Before the patch, 0 was the
invalid value, but as 0 is a valid bus number, the patch changed this to
-1.

However, the fact was missed that many board files do not define the bus
number at all, thus it's left to 0. This causes the driver to fail to
get the i2c bus, exiting from the driver's probe with an error, meaning
that the DVI output does not work for those boards.

This patch fixes the issue by changing the i2c_bus number field in the
driver's platform data from u16 to int, and setting the bus number to -1
in the board files for the boards that did not define the bus. The
exception is devkit8000, for which the bus is set to 1, which is the
correct bus for that board.

The bug exists in v3.5+ kernels.

This patch cleans the bit definition for WINCON register.
The bit definition for WINCON1 and WINCON2 is removed, because

b2c7d54f72 OMAPDSS: get the dss version from core pdev
The output drivers get the omapdss hw version from the platform data for
their respective output device. This doesn't work with DT, as there's no
platform data for them.

Add a new function, omapdss_get_version(), which returns the dss version
from the core device, which will have platform data on DT also. The
function is exported so that users of omapdss can also use it.

The panel drivers contain enable, disable, suspend and resume calls.
The suspend and resume are effectively identical to disable and enable.

This patch removes panel suspend and enable code from omapdss and the

Add new enum, omapdss_version, that is used to tell which DSS hardware
version the SoC has. This enum is initialized during platform init, and
passed in the platform data to omapdss driver.

Note that the versions are not "continuous", that is, you cannot check
if the version is less or greater than something, but you need to check
for exact version match. In other words, this is invalid:

/* test if DSS is 3630 or earlier */
if (ver <= OMAPDSS_VER_OMAP3630)

0febd3bccf Omapdss driver changes for the 3.7 merge window.
Notable changes:
 
 * Basic writeback support for DISPC level. Writeback is not yet usable, though,
   as we need higher level code to actually expose the writeback feature to
   userspace.
 * Rewriting the omapdss output drivers. We're trying to remove the hard links
   between the omapdss and the panels, and this rewrite work moves us closer to
   that goal.
 * Cleanup and restructuring patches that have been made while working on device
   tree support for omapdss. Device tree support is still some way ahead, but
   these patches are good cleanups in themselves.
 * Basic OMAP5 DSS support for DPI and DSI outputs.
 * Workaround for the problem that GFX overlay's fifo is too small for high
   resolution scenarios, causing underflows.
 * Cleanups that remove dependencies to omap platform code.

749feffa6b OMAPDSS: DISPC: Configure overlay-like parameters in dispc_wb_setup
Create struct omap_dss_writeback_info, this is similar to omap_overlay_info,
the major difference is that there is no parameter which describes the input
size to writeback, this is because this is always fixed, and decided by the
connected overlay or overlay manager. One more difference is that screen_width
is renamed to buf_width, to give the value of stride the writeback buffer has.

Call dispc_ovl_setup_common() through dispc_wb_setup() to configure overlay-like
parameters. The parameters in dispc_ovl_setup_common() which do not hold for
writeback are filled passed as zeroes or false, the code takes care of not
configuring them as they won't possess the needed overlay caps.

d79db85300 OMAPDSS: OVERLAY: Add position and replication as overlay caps
Add position and replication as overlay caps, and pass overlay caps as an
argument to the corresponding functions. Adding position and replication to
overlay caps seems a bit unnecessary, but it allows us to use the
corresponding functions for writeback too.

These caps will be set for all overlays, but not for writeback. This is done
so writeback can reuse dispc_ovl_setup() to the maximum.

Now that an omap_dss_output can be used to link between managers and devices, we
can remove the old way of setting manager and device links. This involves

omap_overlay_manager.
