For the edma node, I can understand we may need to add imx943 specific compatible string, then fullback compatible imx95 string. I do have one concern about other node like lpuart, i2c etc, Is it still necessary to add new compatible string for new soc? Currently I reuse the compatibles as imx95. I know previously we were asked to add new compatible string for peripheral nodes when a new SoC is introduced, do we still need follow that suggestion or some tradeoff? lpuart1: serial@44380000 { compatible = "fsl,imx95-lpuart", "fsl,imx8ulp-lpuart", "fsl,imx7ulp-lpuart"; reg = <0x44380000 0x1000>; BR > Best regards, > Krzysztof
