This should be 2 'oneOf' entries listing out the exact names and index.

This already has a common definition and this conflicts with that. 
'clock-frequency' is a single uint32 or uint64.

Don't need allOf here.

You do need to define how many items.

Looks like a pattern.

pattern: '^ssi(-all|\.[0-9])$'

Already has a type definition. Need to define how many.

No unit-address for 'port', so you don't need 'reg' here.

Assume this already has a type.

Perhaps there's max number of ports that's less than 0xf?

Would be more simple to just always have 'ports'.

Already has a type, just need 'maxItems: 1'.

Stopping here because the rest looks like more of the same comments.

I couldn't understand this.
Do you mean like this ??

   compatible:
     oneOf:
       # for Gen1 SoC
       - items:
=>         - enum:

This needs clock array. Like this

	clock-frequency = <12288000 11289600>;

But I got warning without reg ?
And, renesas,rsnd and/or simple-card sometimes needs reg for port
to handle sound path.

Having "ports" or "port" are case-by-case, not always.

Thank you for your help !!

Sorry, but the type is already defined in the spec. You'll still get
warnings from the common schema and you can't override that here.

Not sure what to suggest. Leave it with a fixme or move to
assigned-clocks-rates instead?

Yeah, because of your $ref from ports.

Why?

This:

port {};

and this:

ports {
  port {};
};

Are treated the same. It's perfectly valid to have 'ports' with a single port.

Given that this is an existing schema we should really try to keep
compatibility :/

As you know, I'm not familiar with yaml base Documentation :/
I want leave it as your fixme if possible.

Yeah, if it needs only 1 port.
If I'm not misunderstanding, We are using it as

	ports {
		port@0 {
			endpoint {}
		};
		port@1 {
			endpoint {}
		};
		....
	};

or simply

	port {
			endpoint {}
	};

And here, sometimes, "port" and "endpoint" both need "reg".

Thank you for your help !!
