which compatible with ti,jia1042 according to second patch.

so just add microchip,mcp2542 after microchip,ata6561

          - enum:
              - microchip,ata6561
              - microchip,mcp2542
                ^^^^^^^^^^^^^^^^
              - ti,tcan1051
          - const: ti,tcan1042

use
	compatible = "microchip,ata6561", "microchip,ata6561" in dts
