i.MX Encrypted Storage Using CAAM Secure Keys, but with integrity protection?

Hello,

On an i.MX8M Nano board, we have CAAM-based encryption implemented as per AN12714 https://www.nxp.com/webapp/Download?colCode=AN12714.

Does anyone has knowledge on how to add the dm-integrity to the setup, on i.MX device? According to https://gitlab.com/cryptsetup/cryptsetup/-/wikis/DMCrypt, dm-crypt device can be set up on the Integrity device.

I'm interested exaclty in the "dmsetup" version, not in the "cryptsetup"+"integritysetup" version, because AN12714 recommends dmsetup over cryptsetup.
