[PATCH 7/7] arm64: dts: allwinner: h616: Add SPDIF device node

[Chen-Yu Tsai <wens@xxxxxxxxxx>]

From: Chen-Yu Tsai <wens@xxxxxxxx>

The H616 SoC has an SPDIF transmitter hardware block, which has the same
layout as the one in the H6, minus the receiver side.

Add a device node for it, and a default pinmux.
