If anyone has any objections, please let me know. ------------------ From: Nícolas F. R. A. Prado commit bbcc6d16dea4b5c878d56a8d25daf996c6b8a1d4 upstream. Commit 4a81656c8eaa ("arm64: dts: mediatek: mt8188: Address binding warnings for MDP3 nodes") caused a regression on the MDP functionality when it removed the MT8195 compatibles from the MDP3 nodes, since the MT8188 compatible was not yet listed as a possible MDP component compatible in mdp_comp_dt_ids. This resulted in an empty output bitstream when using the MDP from userspace, as well as the following errors: mtk-mdp3 14001000.dma-controller: Uninit component inner id 4 mtk-mdp3 14001000.dma-controller: mdp_path_ctx_init error 0 mtk-mdp3 14001000.dma-controller: CMDQ sendtask failed: -22 Add the missing compatible to the array to restore functionality.
