If anyone has any objections, please let me know. ------------------ From: Otto Pflüger commit be0b304eeb8c5f77e4f98f64e58729d879195f2f upstream. The endpoint IDs in the display graph are expected to match the associated display path number, i.e. all endpoints connected to mmsys_ep_main must have reg = <0> and all endpoints connected to mmsys_ep_ext must have reg = <1>. Add the missing ID to all endpoints in the display graph, based on mt8365.dtsi as an existing example that does this correctly.
