I don't see any in-tree. The only A64 DTS that references &spdif at all is
sun50i-a64-pine64.dts, which explicitly disables it:

	/* On Euler connector */
	&spdif {
  		status = "disabled";
	};

I'm leaning toward agreeing with Clement that the sound_spdif node (and also
spdif_out) should be removed altogether from the A64 DTSI.
