[PATCH 01/10] ASoC: sunxi: Add bindings for A23/A33/H3 codec's analog path controls

Show all headers | View raw

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";
