Hi Daoyuan, > Depend on: > [1] https://lore.kernel.org/patchwork/patch/1164746/ > [2] https://patchwork.kernel.org/patch/11703299/ > [3] https://patchwork.kernel.org/patch/11283773/ Can you provide an updated list of dependencies because it seems this patch depends on more than the patch aboves. I applied the related patch series above but there is still missing node ERROR (phandle_references): /soc/mdp-rdma0@14001000: Reference to non-existent node or label "scp" ERROR (phandle_references): /soc/mdp-rdma0@14001000: Reference to non-existent node or label "mutex" It would be even better if you could provide a branch with all the dependencies included. > mmsys: syscon@14000000 { > compatible = "mediatek,mt8183-mmsys", "syscon"; > + mdp-comps = "mediatek,mt8183-mdp-dl", > + "mediatek,mt8183-mdp-dl"; > + mdp-comp-ids = <0 1>; > reg = <0 0x14000000 0 0x1000>; > + mediatek,gce-client-reg = <&gce SUBSYS_1400XXXX 0 0x1000>; > #clock-cells = <1>; > + clocks = <&mmsys CLK_MM_MDP_DL_TXCK>, > + <&mmsys CLK_MM_MDP_DL_RX>, > + <&mmsys CLK_MM_IPU_DL_TXCK>, > + <&mmsys CLK_MM_IPU_DL_RX>; > + }; The kernel is not booting anymore when the 4 clocks above are added, if I remove them I can boot again.
