[linux-sunxi][alsa-devel][PATCH 0/3]Add SPDIF support for Allwinner SoCs

[codekipper at gmail.com]

From: Marcus Cooper <codekipper@gmail.com>

This patch set adds support for the Allwinner SPDIF transceiver as present
on the A10, A20 and A31 SoC boards.

For now just the SPDIF transmitter has been tested on a Mele A2000.

In order for this patch set to be functional we require audio clock patches
which will be delivered separately. For those that are interested I've pushed
the patches here with all the required changes to get SPDIF audio out of the
device.

Thanks in advance,
CK

+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.
+
+Required properties:
+
+  - compatible		: should be one of the following:
+    - "allwinner,sun4i-a10-spdif": for the Allwinner A10 SoC
+    - "allwinner,sun7i-a20-spdif": for the Allwinner A20 SoC
+    - "allwinner,sun6i-a31-spdif": for the Allwinner A31 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.
+	"audio"		  clock from the audio pll.
+	"spdif"		  clock for spdif controller.
+
+Optional:
+
+  - spdif-in		: Enable block for capturing an SPDIF signal.
+
+  - spdif-out		: Enable block for transmitting an SPDIF signal.
+
+Example:
+
+spdif: spdif at 01c21000 {
+	compatible = "allwinner,sun4i-a10-spdif";
+	reg = <0x01c21000 0x40>;

Hi All,
I'm getting a "fatal: 'send-email'" response with the last patch(even
though the dry run of the patch series worked) and I've not been able
to work around it. I'll post it as soon as I can work out what the
issue is,
BR,
CK

[linux-sunxi][alsa-devel][PATCH 2/3] dt-binding: Add sunxi SPDIF machine driver

Is there a particular reason for having 2 separate bindings for one piece of
hardware?

Also, both this binding and the driver bits look almost like imx-audio-spdif.
This seems like unneeded duplication. Can we generalize that and use it? Or
just use simple-card?
