Looking at the addresses above, it looks like you have a device from
the i.MX8M family.

caam module is being correctly autoloaded on imx8mn-evk, for example
on kernel 5.14.6:
https://storage.kernelci.org/stable/linux-5.14.y/v5.14.6/arm64/defconfig/gcc-8/lab-baylibre/baseline-imx8mn-ddr4-evk.html

It works on 5.10.67 too:
https://storage.kernelci.org/stable/linux-5.10.y/v5.10.67/arm64/defconfig/gcc-8/lab-baylibre/baseline-imx8mn-ddr4-evk.html

Which kernel version do you use?
