The existing pipeline has child nodes of ports, panel and MIC is remote-endpoint reference of port@0 of ports.  Adding panel as another child node to DSI is unconventional as pipeline has ports child. However it can be true if MIC is added inside port node like this. dsi { compatible = "samsung,exynos5433-mipi-dsi"; #address-cells = <1>; #size-cells = <0>; port { dsi_to_mic: endpoint { remote-endpoint = <&mic_to_dsi>; }; }; panel@0 { compatible = "samsung,s6e3hf2"; reg = <0>; vdd3-supply = <&ldo27_reg>; vci-supply = <&ldo28_reg>; reset-gpios = <&gpg0 0 GPIO_ACTIVE_LOW>; enable-gpios = <&gpf1 5 GPIO_ACTIVE_HIGH>; }; }; The above pipeline is proper but it requires the DSI input MIC pipeline to update. This patch is trying to add panel at port@1 so-that the entire pipeline before to panel output is untouched.
