I may be missing something, but in imx6qdl.dtsi, we have hdmi: hdmi@120000 { #address-cells = <1>; #size-cells = <0>; reg = <0x00120000 0x9000>; interrupts = <0 115 0x04>; gpr = <&gpr>; clocks = <&clks IMX6QDL_CLK_HDMI_IAHB>, <&clks IMX6QDL_CLK_HDMI_ISFR>; clock-names = "iahb", "isfr"; status = "disabled"; port@0 { reg = <0>; hdmi_mux_0: endpoint { remote-endpoint = <&ipu1_di0_hdmi>; }; }; port@1 { reg = <1>; hdmi_mux_1: endpoint { remote-endpoint = <&ipu1_di1_hdmi>; }; }; }; and in imx6q.dtsi, &hdmi { compatible = "fsl,imx6q-hdmi"; port@2 { reg = <2>; hdmi_mux_2: endpoint { remote-endpoint = <&ipu2_di0_hdmi>; }; }; port@3 { reg = <3>; hdmi_mux_3: endpoint { remote-endpoint = <&ipu2_di1_hdmi>; }; }; }; There are no other occurrences of "fsl,imx6q-hdmi" than in imx6q.dtsi (and no occurrences of "fsl,imx6qdl-hdmi" at all).

The port@[0-3] nodes are currently direct children of the &hdmi node, without the "ports" container node. regards Philipp

Of course. Sorry, I've missed that that was the point. I can include a patch to update imx6q(dl).dtsi in the series. Would that work for you ?

I'm not sure there's an explicit effort in that direction, but I think it would make sense as otherwise DT bindings would be too cumbersome to express in YAML.

There's no requirement for 'ports'. The device's node can be the container. If there's not 'ports', we simply don't have any $ref to graph.yaml#/properties/ports. There was at least one case in the conversions I did. What we don't want is a given binding doing both ways. Though generally for new bindings, I'd recommend having 'ports' if there's more than one.

Convert the i.MX6 HDMI TX text binding to YAML. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> --- Changes since v1: - Only specify maxItems for clocks - Drop reg and interrupts as they're checked in the base schema - Rebase on top of OF graph schema, dropped redundant properties - Fix identation for enum entries - Drop clock-names items, use maxItems only --- .../bindings/display/imx/fsl,imx6-hdmi.yaml | 130 ++++++++++++++++++ .../devicetree/bindings/display/imx/hdmi.txt | 65 --------- 2 files changed, 130 insertions(+), 65 deletions(-) create mode 100644 Documentation/devicetree/bindings/display/imx/fsl,imx6-hdmi.yaml delete mode 100644 Documentation/devicetree/bindings/display/imx/hdmi.txt
