I just took a test on imx6sx-sdb with the identical AMIC route as SabreSD does, but the microphone actually still works even if the same link error occurs. So I think the error doesn't break the function on Sabre SD either...and the reason should be the dts connecting 'IN3R' directly to MICBIAS, which isn't so accurate. For the patch, I think the configuration on imx6sx-sdb would be better. 120 "AMIC", "MICBIAS", 121 "IN3R", "AMIC"; Thanks Nicolin
