Looks like the existing fsl-asoc-card.txt? You should convert to schema and use that. Otherwise, my comments are based on this all being 'new'.
Ok, let's treat it as 'new'
+maintainers:
- Shengjiu Wang shengjiu.wang@nxp.com
+properties:
- compatible:
- enum:
- fsl,imx8mq-audio-ak4458
- fsl,imx8mq-audio-ak4497
- fsl,imx8mq-audio-ak5558
- fsl,imx-audio-ak4497
- fsl,imx-audio-ak4458
- fsl,imx-audio-ak5558
- fsl,imx-audio-ak5552
I continue to not understand why audio bindings need the codec(s) in the compatible strings. Can't you look up the codec thru the audio-codec property?
I will try to remove the codecs type from the compatible string and check the codec type in driver.
- model:
- $ref: /schemas/types.yaml#/definitions/string
- description: User specified audio sound card name
- audio-cpu:
- $ref: /schemas/types.yaml#/definitions/phandle
- description: The phandle of a CPU DAI controller
- audio-codec:
- description: The phandle of Codec DAI controllers, there are two
controllers maximum.
We have the common 'sound-dai' property. See the simple-card.yaml binding.
ok, will use sound-dai.
- audio-asrc:
- $ref: /schemas/types.yaml#/definitions/phandle
- description: The phandle of ASRC. It can be absent if there's no
need to add ASRC support via DPCM.
Needs a vendor prefix.
ok, can be removed in the next version.
- fsl,tdm:
- $ref: /schemas/types.yaml#/definitions/flag
- description: |
This is a boolean property. If present, the TDM mode is enabled.
But this one seems like something that could or should be common.
Ok, I will use the common one in the next version.
