The patch

   ASoC: sunxi: add sun4i SPDIF transceiver

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

+Allwinner Sony/Philips Digital Interface Format (S/PDIF) Controller
+
+The Allwinner S/PDIF audio block is a transceiver that allows the
+processor to receive and transmit digital audio via an coaxial cable or
+a fibre cable.
+For now only playback is supported.
+
+Required properties:
+
+  - compatible		: should be one of the following:
+    - "allwinner,sun4i-a10-spdif": for the Allwinner A10 SoC
+
+  - reg			: Offset and length of the register set for the device.
+
+  - interrupts		: Contains the spdif interrupt.
+
+  - dmas		: Generic dma devicetree binding as described in
+			  Documentation/devicetree/bindings/dma/dma.txt.
+
+  - dma-names		: Two dmas have to be defined, "tx" and "rx".
+
+  - clocks		: Contains an entry for each entry in clock-names.
+
+  - clock-names		: Includes the following entries:
+	"apb"		  clock for the spdif bus.
+	"spdif"		  clock for spdif controller.
+
+Example:
+
+spdif: spdif at 01c21000 {
+	compatible = "allwinner,sun4i-a10-spdif";
+	reg = <0x01c21000 0x40>;
+	interrupts = <13>;
+	clocks = <&apb0_gates 1>, <&spdif_clk>;
+	clock-names = "apb", "spdif";
+	dmas = <&dma 0 2>, <&dma 0 2>;
+	dma-names = "rx", "tx";
+	status = "okay";
+};
