msm8916-modem-qdsp6.dtsi defines model = "msm8916" by default since we
have a standard UCM configuration that configures the typical audio
mixer setup when all outputs/inputs are connected to the digital/analog
codec of the SoC/PMIC. "msm8916-1mic" is exactly the same just with the
SecondaryMic disabled.
Unfortunately these names are effectively limited to 15 chars
(everything after will be cut off), so there is extremely limited
potential for more expressive names. :(

Hm, I think I could do the status = "okay" in msm8916-modem-qdsp6.dtsi.
I don't think it should be enabled by default in the SoC dtsi but there
it would probably be fine. :)
Thanks,
