I agree with the removal of "fsl,imx6q-flexcan", but I don't understand your comment saying that: "With "fsl,imx6q-flexcan" compatible string, i.MX8MP FlexCAN would not work" Why? "fsl,imx8mp-flexcan" is passed as the more specific compatible string and it should match against it first. Please clarify.
