Multiple plane overlay is a feature supported by AMD hardware, but it has specific details that deserve proper documentation. This commit introduces a documentation that describes some of the features, limitations, and use cases for this feature. Part of this documentation came from some discussion in the public upstream [1][2].

Documentation/gpu: Add an explanation about the DCN pipeline

2022-09-01T19:09:39Z

In the DCN code, we constantly talk about hardware pipeline, pipeline, or even just pipes, which is a concept that is not obvious to everyone. For this reason, this commit expands the DCN overview explanation by adding a new section that describes what a pipeline is from the DCN perspective. Changes since V1: - Rewrite the first paragraph that describes AMD hardware pipeline.
