Why not fold the two patches?

For i.MX8MM, it just removes the incorrect fallback compatible, for i.MX8MN, it needs
to replace the incorrect fallback compatible in order to support SoC UID read, so I think
this should be 2 separate patch?

Thanks,
Anson.

Oh, yes, there is a subtle difference in the file name :) m|n. I understand
now why you splitted it.

Compared to i.MX7D, i.MX8MM has different ocotp layout, so it should
NOT use "fsl,imx7d-ocotp" as ocotp's fallback compatible, remove it.

Use "fsl,imx8mm-ocotp" as i.MX8MN ocotp's fallback compatible instead
of "fsl,imx7d-ocotp" to support SoC UID read, as i.MX8MN reuses
i.MX8MM's SoC ID driver.
