Merge branch 'archit/wb-dispc-for-3.7'

Merge omapdss writeback work. These patches implement the low level writeback
features in the DISPC, but do not yet add a way to actually use the writeback
from the userspace.

* archit/wb-dispc-for-3.7:
  OMAPDSS: DISPC: Configure color conversion coefficients for writeback
  OMAPDSS: DISPC: Add manager like functions for writeback
  OMAPDSS: DISPC: Configure writeback FIFOs
  OMAPDSS: DISPC: Configure writeback specific parameters in dispc_wb_setup()
  OMAPDSS: DISPC: Configure overlay-like parameters in dispc_wb_setup
  OMAPDSS: DISPC: Add function to set channel in for writeback
  OMAPDSS: DISPC: Don't set chroma resampling bit for writeback
  OMAPDSS: DISPC: Downscale chroma if plane is writeback
  OMAPDSS: DISPC: Configure input and output sizes for writeback
  OMAPDSS: DISPC: Add writeback register offsets and dss features structs
  OMAPDSS: DISPC: Allow both upscaling and downscaling of chroma
  OMAPDSS: DIPSC: Relax scaling limitations when in memory to memory mode
  OMAPDSS: DISPC: Don't pass channel out when configuring overlays
  OMAPDSS: DISPC: Make dispc_ovl_setup call dispc_ovl_setup_common
  OMAPDSS: OVERLAY: Add position and replication as overlay caps
  OMAPDSS: DISPC: Pass overlay caps as a parameter to dispc plane functions
  OMAPDSS: DISPC: Simplify function names for setting pipeline input and output sizes
  OMAPDSS: DISPC: Constify omap_overlay_info in dispc_ovl_setup()
