Aha, thanks. I was doing wild experiments to get something that
boots... I turned them off.

Ok, that certainly changed things; I am now getting this:

Indeed the dts does not seem to contain any gpios

soundcard {
compatible = "audio-graph-card";
label = "Droid 4 Audio";

simple-graph-card,widgets =
"Speaker", "Earpiece",
"Speaker", "Loudspeaker",
"Headphone", "Headphone Jack",
"Microphone", "Internal Mic";

simple-graph-card,routing =
"Earpiece", "EP",
"Loudspeaker", "SPKR",
"Headphone Jack", "HSL",
"Headphone Jack", "HSR",
"MICR", "Internal Mic";

dais = <&mcbsp2_port>, <&mcbsp3_port>;
};

Any more ideas? :-)

Thanks,

Pavel
