The codec in the V3s is similar to the one found on the A31. One key difference is the analog path controls are routed through the PRCM block. This is supported by the sun8i-codec-analog driver, and tied into this codec driver with the audio card's aux_dev. In addition, the V3s does not have LINEIN, LINEOUT, MBIAS and MIC2, MIC3, and the FIFO related registers are like H3.

|
|
- 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:

|
Required properties for the following compatibles:
|
|
- "allwinner,sun6i-a31-codec"
