Would you also have the schematics for the SOM board? I tooked a quick look and I see a ALC5635 codec, but the dts shows WM8524 instead. Which one is correct? > If I applied this change, I won't be able to boot the board, due to > the U-Boot dependence. > Should I try to apply the U-Boot mainline support first? You could build the mainline dtb and rename it with the fsl prefix locally so you could boot test it. Forgot to mention, but you also need to add a separate patch that adds this board entry into Documentation/devicetree/bindings/arm/fsl.yaml Regards, Fabio Estevam
