optee: bind the TA drivers on OP-TEE node
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
node, allowing to identify by phandle the driver
provided by the TA for one UCLASS without modifying
device tree.
