Dear Yocto Community,

we struggle to setup the caam-keygen driver for NXP imx7 chip. The aim is t=
o create an encrypted part of the storage like it is done here: https://www=
.marcusfolkesson.se/blog/encrypted-storage-on-imx/.

Therefore we activated the camm-keygen in the deconfig:

zcat /proc/config.gz | grep -i caam

CONFIG_TRUSTED_KEYS_CAAM=3Dy
CONFIG_CRYPTO_DEV_FSL_CAAM_COMMON=3Dy
CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API_DESC=3Dy
CONFIG_CRYPTO_DEV_FSL_CAAM_AHASH_API_DESC=3Dy
CONFIG_CRYPTO_DEV_FSL_CAAM=3Dy
# CONFIG_CRYPTO_DEV_FSL_CAAM_DEBUG is not set
CONFIG_CRYPTO_DEV_FSL_CAAM_JR=3Dy
CONFIG_CRYPTO_DEV_FSL_CAAM_RINGSIZE=3D9
# CONFIG_CRYPTO_DEV_FSL_CAAM_INTC is not set
CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API=3Dy
CONFIG_CRYPTO_DEV_FSL_CAAM_AHASH_API=3Dy
CONFIG_CRYPTO_DEV_FSL_CAAM_PKC_API=3Dy
CONFIG_CRYPTO_DEV_FSL_CAAM_RNG_API=3Dy
CONFIG_CRYPTO_DEV_FSL_CAAM_PRNG_API=3Dy
CONFIG_CRYPTO_DEV_FSL_CAAM_BLOB_GEN=3Dy
# CONFIG_CRYPTO_DEV_FSL_CAAM_RNG_TEST is not set

But when starting up the device registration is not complete:

~:# dmesg | grep caam

[=C2=A0=C2=A0=C2=A0 1.544624] caam 30900000.crypto: device ID =3D 0x0a16030=
000000000 (Era 8)

[=C2=A0=C2=A0=C2=A0 1.578480] caam 30900000.crypto: rng crypto API alg regi=
stered prng-caam

* Regarding NXP there should be an entry *=E2=80=9CDevice caam-keygen regis=
tered=E2=80=9D -* but this is missing ** is missing?

With the nxp kernel [linux-imx](https://github.com/nxp-imx/linux-imx) the d=
river is working - but many other things does not work - that=C2=B4s why we=
 aim to stay on meta-freescale.

Is there support for the crypto drivers? Have we overseen something during =
activation?

Thanks in advance and best regards,
Tommy
