and platform code
{"Mic Bias", NULL, "MIC"},
{"MIC_IN", NULL, "MIC"},
No, the bias should be a supply for the microphone - ensuring that this happens is the whole point of the patch I sent the other day.

The "MIC" above is confusing. I guess the following that I have in machine driver might be a little clearer.
{"Mic Bias", NULL, "Mic Jack"}, {"MIC_IN", NULL, "Mic Bias"},
And I need to present it in device tree though.

This should be something like:
{ "Mic Jack", NULL, "Mic Bias" }, { "MIC_IN", NULL, "Mic Bias" },
(with the conversion of Mic Bias to a supply widget) which has the bonus of being a whole lot easier to understand.
And I need to present it in device tree though.
Use the generic stuff that Stephen put into the core for reading machine driver routing maps out of the device tree (unless there's some problem with it, but it should work).

Indeed. With your patch, Mic Bias is a supply widget now.

This should be something like:
{ "Mic Jack", NULL, "Mic Bias" }, { "MIC_IN", NULL, "Mic Bias" },
"MiC Bias" --> "Mic Jack" should be enough. Why do we have "Mic Bias" --> "MIC_IN" ?
Thanks Richard

Probably because I've misread what you're trying to do above - if it's just a single variation.
