Currently, the functions below take the omap_plane parameter and derive the
overlay caps within them. Pass the overlay caps as a parameter to the function
to allow writeback functions to use them too.
- dispc_ovl_set_zorder()
- dispc_ovl_set_pre_mult_alpha()
- dispc_ovl_setup_global_alpha()
- dispc_ovl_calc_scaling()
- dispc_ovl_setup()
These functions will be used for writeback later, and the caps will help in
deciding if they are to be used for writeback or not. This allows reuse of
overlay caps for writeback.
