* the graphics output. One of the main features of this component is
* that each pipe has a configurable DET buffer which means that when a
* pipe is not enabled, the device can assign the memory to other
* enabled pipes to try to be more efficient.
*
* DET logic is handled by dchubbub. Some ASICs provide a feature named
* Configurable Return Buffer (CRB) segments which can be allocated to
* compressed or detiled buffers.
