Are you sure these are devices from similar class/type? Your big if:then: block suggests this could be separate binding. Best regards, Krzysztof

Ideally I would have wanted to place the compatible inside dsp/fsl,dsp.yaml as the programming model would have been more similar. Unfortunately, these are different physical devices (HiFi DSP core vs CM core) even though they're all used for DSP purposes so I'm not sure this is entirely appropriate. Alternatively, if you think grouping these devices (i.e: those represented by the -dsp compatibles from fsl,dsp and the one represented by the compatible introduced here) under the same binding is alright we can just branch off from fsl,dsp and fsl,imx-rproc and create a new binding for these devices. I'm expecting this to be relatively clean as they have the same programming model. Let me know your thoughts on this. > > Best regards, > Krzysztof >

That doesn't matter too much. trivial-devices.yaml is a bunch of completely unrelated devices which happen to have the same binding. We could probably take that farther with things like trivial clock providers for example. Having 'reg' vs not is pretty clearly something that should be different binding. > > Alternatively, if you think grouping these devices (i.e: those represented by the -dsp compatibles > from fsl,dsp and the one represented by the compatible introduced here) under the same binding > is alright we can just branch off from fsl,dsp and fsl,imx-rproc and create a new binding for > these devices.

If it's more than that, then I'd make a new binding doc. Rob
