If anyone has any objections, please let me know. ------------------ From: Chen-Yu Tsai commit 3079fb09ddac159bd8bb87f6f15b924e265f8d4d upstream. The DPI display interface feeds the external display pipeline. However the pipeline representation is currently incomplete. Efforts are still under way to come up with a way to represent the "creative" repurposing of the DP bridge chip's internal output mux, which is meant to support USB type-C orientation changes, to output to one of two type-C ports. Until that is finalized, the external display can't be fully described, and thus won't work. Even worse, the half complete graph potentially confuses the OS, breaking the internal display as well. Disable the external display interface across the whole Corsola family until the DP / USB Type-C muxing graph binding is ready.
