For complex display hardware, you may want to consider using the drm
kms infrastructure rather than the kernel fb interface.  It provides
an API for complex display hardware (multiple encoders, display
controllers, etc.) and also provides a legacy kernel fb interface for
compatibility.  See:
Documentation/DocBook/drm.tmpl
drivers/gpu/drm/
in the kernel tree.
