[PATCH V3 0/5] arm: samsung: Move FIMD headers to include/video/

This patchset moves the contents of regs-fb-v4.h and regs-fb.h from arch side
to include/video/samsung_fimd.h

This patchset is created and rebased against master branch of torvalds tree.
Tested on smdk5250 board, build tested for other boards.

Changes from version 2:
	- Changed the EXYNOS5_xxx macro name to FIMD_V8_xxx
	- Moved the header inclusion under same kind

Changes from version 1:
	- Split the patches as per Sylwester comments
	- Changed FIMD_V8_xxx macro to EXYNOS5_xxx	

Leela Krishna Amudala (5):
  include/video: Add samsung FIMD register header
  include/video: Add Exynos5 specific FIMD register offsets
  arm: samsung: Include the modified FIMD header file
  driver: Include the modified FIMD header file
  arm: samsung: delete frame buffer header files from platform
