       deprecated: true

It should be a child node.

Should I add the touchscreen node to
Documentation/devicetree/bindings/arm/bcm/raspberrypi,bcm2835-firmware.yaml
and remove Documentation/devicetree/bindings/input/touchscreen/raspberrypi,firmware-ts.yaml
from this patch?

Thanks and regards,
Dario
