[PATCH v2] dt-bindings: samsung,mipi-dsim: Use port-base reference

[Fabio Estevam]

From: Fabio Estevam <festevam@denx.de>

Use port-base reference for port@1.

This fixes the following schema warning:

imx8mp-dhcom-pdk3.dtb: dsi@32e60000: ports:port@1:endpoint: Unevaluated properties are not allowed ('data-lanes' was unexpected)
From schema: Documentation/devicetree/bindings/display/bridge/samsung,mipi-dsim.yaml

Fixes: 1f0d40d88f7a ("dt-bindings: bridge: Convert Samsung MIPI DSIM bridge to yaml")

Signed-off-by: Fabio Estevam <festevam@denx.de>

Changes since v1:
- Only changed port@1.
- Used Documentation/devicetree/bindings/display/bridge/renesas,dsi.yaml as reference. (Thanks Marek for the suggestion!)

To reproduce the original problem against linux-next 20230531:

- Enable the mipi_dsi node on imx8mp-dhcom-som.dtsi

 &mipi_dsi {
        samsung,burst-clock-frequency = <160000000>;
        samsung,esc-clock-frequency = <10000000>;
+       status = "okay";
 
        ports {
                port@1 {
