[PATCH 1/5] dt-bindings: sound: sun4i-spdif: Fix dma-names warning

[Maxime Ripard]

From: Maxime Ripard <maxime.ripard@bootlin.com>

Even though the H6 compatible has been properly added, the exeption for the
number of DMA channels hasn't been updated, leading in a validation
warning.

Fix this.

[PATCH 2/5] dt-bindings: sound: Convert Allwinner A10 codec to a schema

[Maxime Ripard]

From: Maxime Ripard <maxime.ripard@bootlin.com>

The Allwinner SoCs have an embedded audio codec that is supported in Linux,
with a matching Device Tree binding.

Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.

-Allwinner SUN8I audio codec
-------------------------------------
-
-On Sun8i-A33 SoCs, the audio is separated in different parts:
-	  - A DAI driver. It uses the "sun4i-i2s" driver which is
-	  documented here:
-	  Documentation/devicetree/bindings/sound/allwinner,sun4i-a10-i2s.yaml
-	  - An analog part of the codec which is handled as PRCM registers.
-	  See Documentation/devicetree/bindings/sound/sun8i-codec-analog.txt
-	  - An digital part of the codec which is documented in this current
-	  binding documentation.
-	  - And finally, an audio card which links all the above components.
-	  The simple-audio card will be used.
-	  See Documentation/devicetree/bindings/sound/simple-card.txt
-
-This bindings documentation exposes Sun8i codec (digital part).
-
-Required properties:
-- compatible: must be "allwinner,sun8i-a33-codec"
-- reg: must contain the registers location and length
-- interrupts: must contain the codec interrupt
-- clocks: a list of phandle + clock-specifer pairs, one for each entry
-  in clock-names.
-- clock-names: should contain followings:
-   - "bus": the parent APB clock for this controller
-   - "mod": the parent module clock
-
-Here is an example to add a sound card and the codec binding on sun8i SoCs that
-are similar to A33 using simple-card:
-
-	sound {
-		compatible = "simple-audio-card";
-		simple-audio-card,name = "sun8i-a33-audio";
-		simple-audio-card,format = "i2s";
-		simple-audio-card,frame-master = <&link_codec>;

-		simple-audio-card,mclk-fs = <512>;
-		simple-audio-card,aux-devs = <&codec_analog>;
-		simple-audio-card,routing =
-				"Left DAC", "Digital Left DAC",
-				"Right DAC", "Digital Right DAC";
-
-		simple-audio-card,cpu {
-			sound-dai = <&dai>;
-		};
-
-		link_codec: simple-audio-card,codec {
-			sound-dai = <&codec>;

At some point we should start listing the endpoints available for routing?

Yeah, we should do that. I'm not sure how easy it would be using the
schemas though.

[PATCH 4/5] dt-bindings: sound: Convert Allwinner A23 analog codec to a schema

[Maxime Ripard]

From: Maxime Ripard <maxime.ripard@bootlin.com>

The Allwinner A23 SoC and later have an embedded audio codec that uses a
separate controller to drive its analog part, which is supported in Linux,
with a matching Device Tree binding.

Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.

Please use subject lines matching the style for the subsystem.  This
makes it easier for people to identify relevant patches.  This
doesn't even have ASoC in it...
