If you know the process, you can skip it (please do not feel offended by me posting it here - no bad intentions intended). If you do not know the process, here is a short explanation: Please add Acked-by/Reviewed-by/Tested-by tags when posting new versions, under or above your Signed-off-by tag. Tag is "received", when provided in a message replied to you on the mailing list. Tools like b4 can help here. However, there's no need to repost patches *only* to add the tags. The upstream maintainer will do that for tags received on the version they apply. https://elixir.bootlin.com/linux/v6.5-rc3/source/Documentation/process/submitting-patches.rst#L577 </form letter> Best regards, Krzysztof

Add properties for configuring the MICBIAS pins as general purpose outputs, with some limitations: The voltage on the pin when activated may be set using another property to 2.0 V, 2.5 V or AVDD. When deactivated the pin will float.
