The fsl,imx8mn-ocotp is actually compatible with "mm", only the fsl,imx8mp-ocotp is not (although someone might argue that subset of "mp" falls into "mn"). The problem is that drivers/soc/imx/soc-imx8m.c checks revision only against the fsl,imx8mm-ocotp compatible, not the others. It's the pattern used in that driver also for other i.MX 8. Therefore it is a binding implemented and actually used, regardless whether it is correct from hardware point of view or not. If that's preferred, I could adjust the drivers/soc/imx/soc-imx8m.c for the incompatible "mp". It should not break anything. Best regards, Krzysztof
