Thanks. > Thank you for pulling in the changes! Can you also pull in the patch series titled - TEE driver for AMD APUs? It is related to this patch series. Jens who is the TEE subsystem maintainer has given an Acked-by for the patch series. Please refer link: https://lkml.org/lkml/2019/12/16/608 Thanks, Rijo
