169 * pipe types are identified based on MUXes in DCN front end that are capable
170 * of taking input from one DCN pipeline to another DCN pipeline. The name is
171 * in a form of XXXX_YYYY, where XXXX is the DCN front end hardware block the
172 * pipeline ends with and YYYY is the rendering role that the pipe is in.
