+         This driver exposes a DICE reserved memory region to userspace via
+         a character device. The memory region contains Compound Device
+         Identifiers (CDIs) generated by firmware as an output of DICE
+         measured boot flow. Userspace can use CDIs for remote attestation
+         and sealing.
