|
|
- "allwinner,sun6i-a31-codec"
|
|
- "allwinner,sun7i-a20-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
|
|

|
- "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.
|
