158  * pipe types are identified based on MUXes in DCN front end that are capable
159  * of taking input from one DCN pipeline to another DCN pipeline. The name is
160  * in a form of XXXX_YYYY, where XXXX is the DCN front end hardware block the
161  * pipeline ends with and YYYY is the rendering role that the pipe is in.
162  *
163  * For instance OTG_MASTER is a pipe ending with OTG hardware block in its
164  * pipeline and it is in a role of a master pipe for timing generation.
