   8  * S3C Platform - new-style framebuffer register definitions
   9  *
  10  * This is the register set for the new style framebuffer interface
  11  * found from the S3C2443 onwards into the S3C2416, S3C2450 and the
  12  * S3C64XX series such as the S3C6400 and S3C6410.
  13  *
  14  * The file does not contain the cpu specific items which are based on
  15  * whichever architecture is selected, it only contains the core of the
  16  * register set. See <mach/regs-fb.h> to get the specifics.
  17  *
  18  * Note, we changed to using regs-fb.h as it avoids any clashes with
  19  * the original regs-lcd.h so out of the way of regs-lcd.h as well as
  20  * indicating the newer block is much more than just an LCD interface.
