Default embed this configuration. If OP-TEE PTA RNG is present as well, the priority will be given to it instead of the U-Boot driver.
Are you relying here on drivers being probed in alphabetical sequence?

Hello Heinrich,
I've made a strange wording here.
OP-TEE RNG PTA shouldn't be exposed if the RNG is non-secure as it shouldn't be handled by the secure world. If it is, it is a bad OP-TEE configuration.
On the contrary, if the RNG OPTEE PTA is exposed, then the OP-TEE RNG PTA should be used. Therefore, the RNG node status shouldn't be set to "okay" in U-boot's device tree.
Hope this solves the confusion, I'll reword the sentence.
Best regards, Gatien
