The FEC driver OF match table suggests that fsl,imx6ul-fec and fsl,imx6q-fec
are not really compatible.

static const struct of_device_id fec_dt_ids[] = {
        { .compatible = "fsl,imx25-fec", .data = &fec_devtype[IMX25_FEC], },
        { .compatible = "fsl,imx27-fec", .data = &fec_devtype[IMX27_FEC], },
        { .compatible = "fsl,imx28-fec", .data = &fec_devtype[IMX28_FEC], },
        { .compatible = "fsl,imx6q-fec", .data = &fec_devtype[IMX6Q_FEC], },
        { .compatible = "fsl,mvf600-fec", .data = &fec_devtype[MVF600_FEC], },
        { .compatible = "fsl,imx6sx-fec", .data = &fec_devtype[IMX6SX_FEC], },
        { .compatible = "fsl,imx6ul-fec", .data = &fec_devtype[IMX6UL_FEC], },
        { .compatible = "fsl,imx8mq-fec", .data = &fec_devtype[IMX8MQ_FEC], },
        { .compatible = "fsl,imx8qm-fec", .data = &fec_devtype[IMX8QM_FEC], },
        { /* sentinel */ }
};
MODULE_DEVICE_TABLE(of, fec_dt_ids);

Should we fix the binding doc?
