When the RNG device is secured with OP-TEE, it is only accessible with the HWRNG TA, the CONFIG_RNG_OPTEE is needed for STM32MP15 targets with OP-TEE support.
The probe of this RNG driver fails when the TA is not available in OP-TEE and the previous driver can be used, as CONFIG_RNG_STM32MP1 is activated and when the associated node is activated in the device tree with:
&rng1 { status = "okay"; };
When the RNG is used in OP-TEE, this node should be deactivated in the Linux and U-Boot device tree.
