[Linaro-mm-sig] [PATCH v2 0/1] tee: Add tee_shm_register_fd

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.

Patch tested on Hikey 6220.
