Hi! >vreg_l14a_1p88: ldo14 { >+ regulator-min-microvolt = <1800000>; >+ regulator-max-microvolt = <1800000>; Should probably be renamed to vreg_l14a_1p8 then. >+ ports { >+ port@1 { >+ endpoint { >+ remote-endpoint = <&tianma_nt36672a_in_0>; >+ data-lanes = <0 1 2 3>; >+ }; >+ }; >+ }; The endpoint has a label, you can simply use &dsi0_out {};. >+ vddpos-supply = <&lab>; >+ vddneg-supply = <&ibb>; With Angelo's latest series [1] merged in, I reckon you should explicitly configure lab/ibb (like in [2]), as wrong settings (which CAN BE SET BY THE BOOTLOADER in some instances!!) can lead to hardware damage.
