Subject[PATCH v2 0/1] tee: Add tee_shm_register_fd
Date
Add a new ioctl called TEE_IOC_SHM_REGISTER_FD to register a
shared memory from a dmabuf file descriptor.
This new ioctl will allow the Linux Kernel to register a buffer
to be used by the Secure Data Path OPTEE OS feature.

Please find more information here:

Patch tested on Hikey 6220.
