There is some mess in this posting. Nothing looks threaded and b4 does not see entire posting. Sorry, don't make it complicated to us. Send proper submission - see numorous guides or submitting-patches - so reviewing will be straightforward. Best regards, Krzysztof

I missed the --thread option when creating the patches. I will resend them properly. Apologies, Jonathan S. >

The AD7768-1 provides a buffered common-mode voltage output on the VCM pin that can be used to bias analog input signals. Add regulators property to enable the use of the VCM output, referenced here as vcm_output, by any other device.
