That's great info, thanks very much. My DT looks like this, inside sound{} I have:
compatible = "fs,imx28-tx28-wm8753", "fsl,mxs-audio-wm8753"; model = "wm8753"; saif-controllers = <&saif0 &saif1>; audio-controllers = <&i2c0>; audio-code = <&wm8753>;
Inside i2c0{} I have:
wm8753: wm8753@1a { Compatible = "wlf,wm8753"; reg = <0x1a>;
I have tried changing model to "wm8753-voice" but still get the same error.
Am I changing it in the wrong place? Or do I need another setting?
I'm very much a beginner at this DT stiff and also configuring and using sound devices so any info you can supply will be of great help.

Hi there
I am attempting to configure a Wolfson WM8753 on a Ka-Ro TX28S, I was wondering if you had any success managing this and if you could give me some pointers. Currently, I think my device tree may be wrong. I am getting this message on bootup:
mxs-wm8753 sounds.12: ASoC: CODEC DAI wm8753 not registered
It does indeed sound like your DT is wrong. "wm8753" is not the name of any of the DAIs on the device. The two DAIs are called "wm8753-hifi" and "wm8753-voice".
Thanks, Charles
