Patch Review

This patch adds the `dpi-bridge` subnode schema and a binding example.

**Observations:**

The binding looks well-structured. It properly references `graph.yaml` and `video-interfaces.yaml` for ports and endpoint properties. The `bus-width` enum restricts to valid values `[16, 18, 24]` and the documentation explains the truncation behavior clearly.

One minor question: the binding defines both `nxp,imx91-pdfc` and `nxp,imx93-pdfc` as compatible strings, but the driver (patch 2) only matches `nxp,imx93-pdfc`. The DTS (patch 3) uses `nxp,imx93-pdfc` in the common dtsi for both SoCs. If the imx91 compatible is intended for future use, that's fine, but if someone were to use `nxp,imx91-pdfc` in a device tree today, the driver would not probe. It would be cleaner to either add `nxp,imx91-pdfc` to the driver's `of_device_id` table now, or document that imx91 should use a fallback compatible pair.

No issues with the binding schema itself.
