Documentation/devicetree/bindings/input/touchscreen/touchscreen.yaml:
horizontal resolution of touchscreen (maximum x coordinate reported + 1)

So this touchscreen reports max 1278?

> +             touchscreen-size-y = <799>;

same question.

And these things belong below rm4-f11 according to
Documentation/devicetree/bindings/input/syna,rmi4.yaml
