Maybe drop the node, and people who need it whould reintroduce it properly?

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.

Yeah, I agree, it's pretty much what we've been doing in other SoCs. Especially if we don't have any DT in-tree using it, we don't really have any incentive to make it common. Maxime
