Hi,

As mentioned earlier, this isn't a documented compatible string. So,
I guess without overwriting this in the board dts it will throw an
error with the dt schema validator. OTOH, there are many dtsi files
in arch/arm/boot/dts/ doing this. I don't know what is correct here.

I see it documented here:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/arm/atmel-at91.yaml#n165

Isn't it what is expected?

That only documents
    compatible = "microchip,lan9662-pcb8291", "microchip,lan9662",
"microchip,lan966";

But not the one above.

Oh, you mean the "microchip,lan966" string alone in the compatibility string and not with the other ones before it... I didn't know it could be different in yaml syntax. Thanks for highlighting that.

Best regards,

Everthing else looks good.

Thanks a lot for your reviews.

I'm queuing it to at91-dt branch for reaching arm-soc in 5.18 merge
window.

Nice, then I'm good to go for my patches on top of this :)
