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.

Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com>

---

Changes from v2:
  - Change the audio-routing values to an enum, and enforce boundaries on
    the size
  - Add restrictions to the possible values of audio-routing

Changes from v1:
  - Fix subject prefix

This looks like the same list as the default...

-* Allwinner A10 Codec
-
-Required properties:
-- compatible: must be one of the following compatibles:
-		- "allwinner,sun4i-a10-codec"
-		- "allwinner,sun6i-a31-codec"
-		- "allwinner,sun7i-a20-codec"
-		- "allwinner,sun8i-a23-codec"
-		- "allwinner,sun8i-h3-codec"
-		- "allwinner,sun8i-v3s-codec"
-- reg: must contain the registers location and length
-- interrupts: must contain the codec interrupt
-- dmas: DMA channels for tx and rx dma. See the DMA client binding,
-	Documentation/devicetree/bindings/dma/dma.txt
-- dma-names: should include "tx" and "rx".
-- clocks: a list of phandle + clock-specifer pairs, one for each entry
-  in clock-names.
-- clock-names: should contain the following:
-   - "apb": the parent APB clock for this controller
-   - "codec": the parent module clock
-
-Optional properties:
-- allwinner,pa-gpios: gpio to enable external amplifier
-
-Required properties for the following compatibles:
-		- "allwinner,sun6i-a31-codec"
-		- "allwinner,sun8i-a23-codec"
-		- "allwinner,sun8i-h3-codec"
-		- "allwinner,sun8i-v3s-codec"
-- resets: phandle to the reset control for this device
-- allwinner,audio-routing: A list of the connections between audio components.
-			   Each entry is a pair of strings, the first being the
-			   connection's sink, the second being the connection's
-			   source. Valid names include:
-
-			   Audio pins on the SoC:
-			   "HP"
-			   "HPCOM"
-			   "LINEIN"	(not on sun8i-v3s)
-			   "LINEOUT"	(not on sun8i-a23 or sun8i-v3s)
-			   "MIC1"
-			   "MIC2"	(not on sun8i-v3s)
-			   "MIC3"	(sun6i-a31 only)
-
-			   Microphone biases from the SoC:
-			   "HBIAS"
-			   "MBIAS"	(not on sun8i-v3s)
-
-			   Board connectors:
-			   "Headphone"
-			   "Headset Mic"
-			   "Line In"
-			   "Line Out"
-			   "Mic"
-			   "Speaker"
