Kernel-4.18.0-80.el8_sun4i-codec

• 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"
  

Required properties for the following compatibles:
- “allwinner,sun8i-a23-codec”
- “allwinner,sun8i-h3-codec”
- “allwinner,sun8i-v3s-codec”

• allwinner,codec-analog-controls: A phandle to the codec analog controls

               block in the PRCM.
