[PATCH] arm64: zynqmp: Add an OP-TEE node to the device tree
Since the zynqmp boards can run upstream OP-TEE, and having the DT node present doesn't cause any side effects add it in case someone tries to load OP-TEE.

Then I would expect you will enable it for all boards. It means patch zynqmp.dtsi instead of only one board.
