Please include a cover letter with a changelog in v3.

It sounds like it would be useful to have a fallback in this case:

properties:
  compatible:
    oneOf:
      - const: microchip,mcp9600
      - items:
          - - microchip,mcp9600
          - microchip,mcp9600

>    reg:
>      maxItems: 1

Usage would then be:

	compatible = "microchip,mcp9601", "microchip,mcp9600";
