Hi Patrick
just one typo

In U-Boot driver model the devices can be referenced by phandle in the U-Boot configuration nodes.
Without a valid node provided during the bind, the driver associated to OP-TEE TA can't be referenced.
For example to force the sequence number with alias (.flags = DM_UC_FLAG_SEQ_ALIAS)
aliases { rng0 = &optee; };
or other configuration:
board-sysinfo { compatible = "vendor,sysinfo-board"; ramdom = <&optee>; }
With this patch all drivers bound from OP-TEE service discovery are now associated are associated to OP-TEE
s/are now associated are associated/are now associated
node, allowing to identify by phandle the driver provided by the TA for one UCLASS without modifying device tree.
