Now that you are here ... could you use compatible = "google,cros-ec-spi" here?

The reason is that the label above, cros-ec@0 is not really correct for an i2c
device because after the @ you should put the address, cros-ec@1e will have more
sense here. But cros-ec-i2c is rarely used, so I'd change the compatible to use
"google,cros-ec-spi" and the entry "cros-ec@0" is fine.

And maybe would be useful have a more complete example like this?

cros-ec@0 {
compatible = "google,cros-ec-spi";

usbc_extcon0: extcon@0 {
compatible = "google,extcon-usbc-cros-ec";
google,usb-port-id = <0>;
};


usbc_extcon1: extcon@1 {
compatible = "google,extcon-usbc-cros-ec";
google,usb-port-id = <1>;
};
};

There should also be a 'spi' parent node and 'reg' here.

And no unit-address here as there's no 'reg'.

Thanks for pointing all this, I'll fix current users of this binding, as they
are wrong.
