Add a generic TEE revision sysfs attribute backed by a new optional get_tee_revision() callback. The revision string is diagnostic-only and must not be used to infer feature support.

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.
