dm-integrity volume with TPM key?

[Sebastian Wiesner <sebastian@xxxxxxxx>]

Hello,

"Authenticated Boot and Disk Encryption on Linux" [1] suggests to "make
/home/ its own dm-integrity volume with a HMAC, keyed by the TPM" when
using systemd-homed for user home directories.

I'd like to try that but… how? I can use systemd-cryptenroll to make a
encrypted volume with a TPM key, but how do I make a dm-integrity
volume with a TPM key?  I've gone through the manpage for
integritysetup and did a few unsuccessful google searches, but I've not
found any answer.

I'd appreciate some pointers into the right direction.

Cheers,
Basti
