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 >
