Hm.. I don't like that you enable it within the base dtsi and add the
missing dependencies here. I would rather add the touchscreen within the
base dtsi but with with status set to disabled and without specifying
the interrupt and reset gpio. Within the dts and the below you can
reference the touchscreen via phandle and add the missing properties.
Regards,
Marco
