Description:
		OP-TEE bus provides reference to registered drivers under this directory. The <uuid>
		matches Trusted Application (TA) driver and corresponding TA in secure OS. Drivers
		are free to create needed API under optee-ta-<uuid> directory.
optee: use uuid for sysfs driver entry With the evolving use-cases for TEE bus, now it's required to support multi-stage enumeration process. But using a simple index doesn't suffice this requirement and instead leads to duplicate sysfs entries. So instead switch to use more informative device UUID for sysfs entry like: /sys/bus/tee/devices/optee-ta-<uuid> Signed-off-by: Maxim Uvarov <maxim.uvarov@linaro.org> Reviewed-by: Sumit Garg <sumit.garg@linaro.org> Reviewed-by: Jarkko Sakkinen <jarkko.sakkinen@linux.intel.com> Tested-by: Sumit Garg <sumit.garg@linaro.org> Signed-off-by: Jens Wiklander <jens.wiklander@linaro.org> 2020-06-18 21:52:49 +08:00			`What: /sys/bus/tee/devices/optee-ta-<uuid>/`
