Thanks Vinod for your feedback,

If you look at the *existing* code, we don't handle any "resources" with the
platform devices, we use the platform_device_info.data to pass the link
information. It's a void pointer. We do not touch the resource field in the
platform_device_into at all.

Yes that is true I dont disagree on that part. My ask here is to make it
better, it can be followed up after this but I would at least like to
agree on the direction.

[...]

That's it. We did not change anything else, all the other fields are
identical. We are only changing the TYPE of device and the interfaces for
probe/remove but using the same information and the same device hierarchy.

The move in itself is okay but I dont think that should be the end goal.

What we suggested in this patch is only an iso-functionality change. I believe from Greg's and your feedback that there is no objection on that small step.

This is not the end-goal indeed. The second step would be to remove the intel_init.c file. I fully agree with you Vinod that this can be moved into the SOF driver, and we could do this in a follow-up step. We can also improve the partition between 'context' used by the child driver and information passed by the parent on SHIM registers and bases.

I think we'd need to agree on the details of the second step, Bard and I can work on a proposal, but I don't see a disconnect on the direction to simplify the interface. That's the right thing to do.
