If I do like this in imx51.dtsi: compatible = "fsl,imx51-sahara", "fsl,imx53-sahara"; Then the driver works just fine. I was not sure if this was OK or not because imx51 was introduced prior than imx53 was launched. Would it be OK to use: compatible = "fsl,imx51-sahara", "fsl,imx53-sahara"; ? Thanks
