Re: [PATCH v2 2/2] dt-bindings: dsp: fsl: Add DSP optional clocks documentation

quoted

The H/W block is controlled by the DSP firmware. So, we don't want
to use the Linux kernel driver (thus the H/W block device tree node).

'status' is how you disable a device to not be used by the OS.

The information about that device's resources are already in DT, we
don't need to duplicate that here. If you want a list of devices
assigned to the DSP here, that would be okay.

Thanks! This is a very good idea. I was thinking at a totally different thing.

So having something like this:

dsp {


hw-block-list = <&sai1>, <&sai2>;

}

And then inside the DSP driver we can get access to sai1 clocks. Do
you know of any standard property name?

The only thing that we cannot control from the DSP firmware are the clocks
hence we handle them in the DSP node.

We moved the DAI clocks under the DSP node as I think you suggested here:

No, that's certainly not what I was suggesting. The resources in the
DSP node should be the h/w resources of the DSP itself.

I see thanks!
