It's really just a few lines, unless more than two devicetrees use those, I'm
more for just putting those in cerise.dts and stern.dts instead of having yet
another dtsi to walk through...

You are referencing to the touchscreen at 10 node from mt8183-kukui-jacuzzi.dtsi...

...which is not disabled by default, so this property is useless, and

It's originally elan,ekth3500, you override it with hid-over-i2c, that's ok, but

> +	reg = <0x10>;

the node already has this property....

> +	interrupt-parent = <&pio>; > +	interrupts = <155 IRQ_TYPE_LEVEL_LOW>;

...and this one, actually even better, it's using interrupts-extended instead...

> +	pinctrl-names = "default";
> +	pinctrl-0 = <&touchscreen_pins>;

....and it's the same for this

> +	hid-descr-addr = <0x0001>;

...but those two aren't present.

So you only need three properties in here :-)

Apart from that, there's no google,cerise (nor the skus, of course) in the bindings
so please add those to arm/mediatek.yaml between Burnet and Cozmo; only then I will
be able to accept new board dts.

Thanks!
