ASoC: sunxi: Add bindings for A23/A33/H3 codec's analog path controls
The internal codec on A23/A33/H3 is split into 2 parts. The analog path controls are routed through an embedded custom register bus accessed through the PRCM block. The SoCs share a common set of inputs, outputs, and audio paths. The following table lists the differences. ---------------------------------------- | Feature \ SoC | A23 | A33 | H3 | ---------------------------------------- | Headphone | v | v | | ---------------------------------------- | Line Out | | | v | ---------------------------------------- | Phone In/Out | v | v | | ---------------------------------------- Add a binding for this hardware.

* Allwinner Codec Analog Controls
|
||||
|
||||
Required properties:
|
||||
- compatible: must be one of the following compatibles:
|
||||
- "allwinner,sun8i-a23-codec-analog"
|
||||
- "allwinner,sun8i-h3-codec-analog"
|
||||
|
||||
Required properties if not a sub-node of the PRCM node:
|
||||
- reg: must contain the registers location and length
|
||||
|
||||
Example:
|
||||
prcm: prcm@01f01400 {
|
||||
codec_analog: codec-analog {
|
||||
compatible = "allwinner,sun8i-a23-codec-analog";
|
||||
};
|
