The Allwinner SoCs feature an I2S controller across multiple SoC generations.
Which SoC generations?

The label and node name seems wrong?
Yes, in fact, I don’t know much about yaml format files. The allwinner,sun50i-h6-dmic.yaml file is based on allwinner,sun4i-a10-spdif.yaml. So, How do i convert txt file to yaml file, for example: --------------------------------------------- Required properties:
- compatible : should be one of the following: - "allwinner,sun50i-h6-dmic": for the Allwinner H6 SoC
- reg : physical base address of the controller and length of memory mapped region.
- dmas : Generic dma devicetree binding as described in Documentation/devicetree/bindings/dma/dma.txt.
- dma-names : DMA have to be defined, "rx".
- clocks : Contains an entry for each entry in clock-names.
- clock-names : Includes the following entries: "apb" clock for the dmic bus. "dmic" clock for dmic controller.
- resets : reset specifier for the ahb reset
Example:
dmic: dmic@5095000 { #sound-dai-cells = <0>; compatible = "allwinner,sun50i-h6-dmic"; reg = <0x05095000 0x400>; clocks = <&ccu CLK_BUS_DMIC>, <&ccu CLK_DMIC>; clock-names = "apb", "dmic"; dmas = <&dma 7>; dma-names = "rx"; resets = <&ccu RST_BUS_DMIC>; }; ---------------------------------------------
Thanks.
#sound-dai-cells = <0>;compatible = "allwinner,sun50i-h6-dmic";reg = <0x05095000 0x400>;clocks = <&ccu CLK_BUS_DMIC>, <&ccu CLK_DMIC>;You'll need includes for it to compile
