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.
