Sorry for the late reply.

I assume the correct way would be like:

    oneOf:                                   
      - enum:                                
          - fsl,imx7ulp-lpi2c                
      - items:                               
	  - enum:                            
	      - fsl,imx8dxl-lpi2c            
	      - fsl,imx8qxp-lpi2c            
	      - fsl,imx8qm-lpi2c             
	  - const: fsl,imx7ulp-lpi2c         
				
Right ?

Since all the possible combinations are:
	compatible = "fsl,imx8dxl-lpi2c", "fsl,imx7ulp-lpi2c";
	compatible = "fsl,imx8qm-lpi2c", "fsl,imx7ulp-lpi2c";
	compatible = "fsl,imx8qxp-lpi2c", "fsl,imx7ulp-lpi2c";
	compatible = "fsl,imx7ulp-lpi2c";
