Tegra OP-TEE device tree structure

Dear developers,

I am implementing an OP-TEE I2S driver for the Jetson AGX Xavier. I had a look at the tegra194-optee.dts device tree structure file and noticed there aren’t any entries for I2S. However the device tree structure used by the kernel-5.10 (kernel-5.10/arch/arm64/boot/dts/nvidia/tegra194.dtsi) has entries for I2S.

I will like to know if I am obliged to put an entry for the I2S device in the OP-TEE device tree too for the OP-TEE driver to work correctly, or the entry in the kernel device tree suffices.

Thanks in advance for your response.
