+What:		/sys/class/tee/tee{,priv}X/rpmb_routing_model
+Date:		May 2024
+KernelVersion:	6.10
+Contact:        op-tee@lists.trustedfirmware.org
+Description:
+		RPMB frames can be routed to the RPMB device via the
+		user-space daemon tee-supplicant or the RPMB subsystem
+		in the kernel. The value "user" means that the driver
+		will route the RPMB frames via user space. Conversely,
+		"kernel" means that the frames are routed via the RPMB
+		subsystem without assistance from tee-supplicant. It
+		should be assumed that RPMB frames are routed via user
+		space if the variable is absent. The primary purpose
+		of this variable is to let systemd know whether
+		tee-supplicant is needed in the early boot with initramfs.

+Description:
+		Read-only revision string reported by the TEE driver. This is
+		for diagnostics only and must not be used to infer feature
+		support. Use TEE_IOC_VERSION for capability and compatibility
+		checks.
