[PATCH v2 14/15] ASoC: dt-bindings: renesas,rsnd.yaml: add common port-def

[Kuninori Morimoto]

renesas,rsnd uses both "ports" has "port", and these are very similar.
To avoid duplicated definitions, this patch adds common port-def.

[PATCH v2 15/15] ASoC: dt-bindings: renesas,rsnd.yaml: enable multi ports for multi Component support

[Kuninori Morimoto]

To enable multi Component support, "multi ports" is needed for Audio Graph
Card/Card2, and "multi rcar_sound,dai" is needed for Simple Audio Card.
This patch enable these.

It would be better if users just always used "ports { port {}; };" even 
in the single port case.

With a unit-address you need a 'reg' property.

Multiple 'ports' nodes is not valid.

Here too would need a 'reg' property. Did you test any of this because 
that would be a dtc warning.

Hmm... many drivers are using "definitions" ?
This kind of indication is very confusable...

"ports" support is added, we can't modify past.

I don't remember detail, but some reviewer indicated that it is not needed,
because we have default "reg" property somewhere/somehow.

Patches welcome to change them. I don't think it's many (not counting 
types.yaml). Use of "definitions" or "$defs" is an exception.

> This kind of indication is very confusable...

"definitions" was common convention in early json-schema. "$defs" was 
added to the specification to standardize it.

I don't understand. The graph APIs all work the same with or without 
'ports'. Changing the DT shouldn't affect the ABI.

OK, let's use "$defs" in v3

But, the driver didn't have "ports" handling code, "port" only.
From "DT point of view" changing port -> ports { port {}; }; is no problem,
but "driver code point of view", it is big problem.

I will get error if I used "$defs" instead of "definitions", like below.
There is no error in "definitions" case.
