> -====================
> -
> -A display stream starts at a source function block that reads pixel data from
> -memory and ends with a sink function block that drives pixels on a display
> -interface, or writes pixels back to memory. All DISP function blocks have
> -their own register space, interrupt, and clock gate. The blocks that can
> -access memory additionally have to list the IOMMU and local arbiter they are
> -connected to.
