Subject: goldfish: framebuffer driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.

[sheng@linux.intel.com: cleaned up to handle x86]
[thomas.keel@intel.com: ported to 3.4]
[alan@linux.intel.com: cleaned up for style and 3.7, moved blank methods]
[akpm@linux-foundation.org: fix (silly) sparse warnings]

Subject: 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.

Subject: drivers/video/Kconfig: specify the SoCs that make use of FB_IMX

FB_IMX is the framebuffer driver used by MX1, MX21, MX25 and MX27 processors.

Pass this information to the Kconfig text to make it clear.

Subject: video: s3c-fb: use ARCH_ dependancy

Use ARCH_ dependancy when using s3c-fb.  S3C_DEV_FB, S5P_DEV_FIMD0 cannot
be enabled on EXYNOS5.  So, ARCH_ should be used as dependancy for s3c-fb.
