Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The DT binding example fails schema validation because its `compatible` string array is incomplete and does not match the schema's requirements.

dt-bindings: display: bridge: Document Renesas R-Car V4H DSC bindings

This commit adds device tree bindings for the VESA DSC Display Stream
Compression encoder embedded in the Renesas R-Car V4H SoC. It defines the
schema constraints, required properties, and provides an example node.

[Severity: Low]
Does this example fail dt_binding_check validation? The schema requires the
compatible property to be an array containing exactly two items: the 
SoC-specific string and the fallback constant (renesas,rcar-dsc). However,
the example only provides the SoC-specific string. 

Should the example be updated to match the schema requirements?
