However, the fec of imx8ulp(and imx6ul) is a little different from imx6q, therefore, the functions supported by the driver are also somewhat different. I understand. But if imx8ulp is the same as imx6ul and imx6ul is compatible with imx6q, then I expect imx8ulp to be compatible with imx6ul and with imx6q.
