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.
173 *
174 * For instance OTG_MASTER is a pipe ending with OTG hardware block in its
175 * pipeline and it is in a role of a master pipe for timing generation.
176 *
177 * For quick reference a diagram of each pipe type's areas of responsibility
178 * for outputting timings on the screen is shown below:
