Hm, it is a bit surprising to see some PCM6240-compatible devices 100% different from other PCM6240-compatible. PCM6240 is ADC. DIX4192 is not ADC, not even DAC. How can it be compatible with PCM6240 in such case? Best regards, Krzysztof

PCM6240 is ADC. DIX4192 is not > ADC, not even DAC. How can it be compatible with PCM6240 in such case? I don't know about this specific example but many modern CODECs have a substantial digital component which can usefully be used separately to the analog components in some system designs, sometimes that's still got the digital parts of the ADCs/DACs as PDM inputs and outputs are used but not always even that. We have some devices that are just pure S/PDIF bridges in tree already, and the WM8996 is an example of a CODEC with only PDM.

PCM6240 family chips are popular among audio customers, in spite of only a portion of the functionality of codec, such as ADC or DAC, and so on, for different Specifications, range from Personal Electric to Automotive Electric, even some professional fields.yet their audio performance is far superior to the codec's, and cost is lower than codec, and much easier to program than codec. Signed-off-by: Shenghao Ding <shenghao-ding@ti.com> --- Change in v3: - Rewrite the subject to match something similar to other commits. - And none of them are compatible with something. - minItems, then maxItems. - Drop reset-gpios description - Remove the repeated reg descriptions and reg constraints. - Drop redundant spaces. - Add missing line breaks between blocks and additionalProperties. - Correct compatibility issue on adc6120 and pcm6240. - All these chips have only a portion of the functionality of codec, such as ADC or DAC, and so on, but their audio performance is far superior to the codec's, and cost is lower than codec, and much easier to program than codec. Simply one or two register settings can enable them to work. Init for these chips are hardware reset or software reset. As to some audio filter params for internal filters, it is up to the special user cases, which can be saved into the bin file. The default value also can work well. - Add blank line before reg. - remove unneeded items and if branches. - Add missing compatible devices, such as adc6120, etc. - Add necessary people into the list for DTS review - correct misaligned. --- .../devicetree/bindings/sound/ti,pcm6240.yaml | 214 ++++++++++++++++++ 1 file changed, 214 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/ti,pcm6240.yaml
