How would you imagine connecting a camera to the ports, then? For MDSS, there's a label for the endpoint (mdss_dsi0_out) which the device DTS can then reference: &mdss_dsi0_out { remote-endpoint = <&panel_in>; data-lanes = <0 1 2 3>; }; For CAMSS, the port labels would be used like so: &camss_port1 { camss_endpoint1: endpoint { clock-lanes = <7>; data-lanes = <0 1 2 3>; remote-endpoint = <&cam_front_endpoint>; }; }; Without the labels, the connection might look something like: &camss { status = "okay"; // Modification of existing /soc/isp@acb3000/ports node ports { // Modification of existing /soc/isp@acb3000/ports/port@1 node port@1 { // New node camss_endpoint1: endpoint { clock-lanes = <7>; data-lanes = <0 1 2 3>; remote-endpoint = <&cam_front_endpoint>; }; }; }; }; which I believe is not preferred.

Unavoidably you do have endpoint labels, so it's non-obvious why the version above is better than the next one: &camss_endpoint1 { clock-lanes = <7>; data-lanes = <0 1 2 3>; remote-endpoint = <&cam_front_endpoint>; }; Minus two lines of code, minus one label.

Well, that's exactly how it's done right at the moment, in other words it was preferred every time in the past. -- Best wishes, Vladimir

Port labels are not needed. Thanks for having me look into this. In DTSI: ports { #address-cells = <1>; #size-cells = <0>; camss_port0: port@0 { reg = <0>; camss_endpoint0: endpoint { }; }; camss_port1: port@1 { reg = <1>; camss_endpoint1: endpoint { }; }; camss_port2: port@2 { reg = <2>; camss_endpoint2: endpoint { }; }; }; The example above doesn't work as-is. [ 15.387215] qcom-camss acb3000.camera-controller: Cannot get remote parent [ 15.387604] qcom-camss acb3000.camera-controller: probe with driver qcom-camss failed with error -22 However, the camss_of_parse_ports function has a way to make it work, even if all endpoint nodes are present. In DTSI: ports { #address-cells = <1>; #size-cells = <0>; camss_port0: port@0 { reg = <0>; camss_endpoint0: endpoint { status = "disabled"; }; }; camss_port1: port@1 { reg = <1>; camss_endpoint1: endpoint { status = "disabled"; }; }; camss_port2: port@2 { reg = <2>; camss_endpoint2: endpoint { status = "disabled"; }; }; }; In DTS: &camss_endpoint1 { clock-lanes = <7>; data-lanes = <0 1 2 3>; remote-endpoint = <&cam_front_endpoint>; status = "okay"; }; I didn't know how to make the working example.
