[PATCH] arm64: dts: rockchip: add spdif sound node for rock64

[Katsuhiro Suzuki]

This patch adds sound card node for rock64. Currently we can support
S/PDIF only. It seems the lack of codec driver of rk3328 to enable
analog audio out.

[PATCH v2] arm64: dts: rockchip: add i2s and spdif endpoints of rk3328
