Convert the IFI CAN-FD controller binding from free-form text to DT schema, and reference the common can-controller.yaml schema. The driver matches on the "ifi,canfd-1.0" compatible and obtains its interrupt through platform_get_irq(), so interrupts is required and no additional properties are used. --- v2: - Correct the description: this is a soft IP block typically synthesised into an FPGA or CPLD, not a controller found on Renesas SoCs. Wording now follows the driver's Kconfig entry. v3: - Use unevaluatedProperties: false instead of additionalProperties: false. As can-controller.yaml is referenced through allOf, additionalProperties would have rejected properties defined by that common schema, such as termination-gpios and termination-ohms.
