[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

The Allwinner SoCs have an embedded audio codec that is supported in Linux,

[PATCH 3/5] dt-bindings: sound: Convert Allwinner A33 codec to a schema

[Maxime Ripard]

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

The Allwinner A33 SoC 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:

[PATCH 5/5] dt-bindings: sound: Convert Allwinner A64 analog codec to a schema

[Maxime Ripard]

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

The Allwinner A64 SoC has 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.

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

Please use subject lines matching the style for the subsystem.  This
makes it easier for people to identify relevant patches.  This
