 module_param_named(source, trusted_key_source, charp, 0);
-MODULE_PARM_DESC(source, "Select trusted keys source (tpm or tee)");
+MODULE_PARM_DESC(source, "Select trusted keys source (tpm, tee or caam)");

I didn't closely follow the previous discussions, but is a module
parameter really the right approach?
Is there also a way to set it via something like device tree?

It's there to support a platform which possesses multiple trusted keys
backends. So that a user is able to select during boot which one to
use as a backend.

I understand the use case, my question was whether it makes actually sense to
have a module parameter for it, or additionally another way to define the
preferred backend.

Thanks,
