Hi Jyri.

dt_binding_check gives following warning:
 CHECK   Documentation/devicetree/bindings/display/ti/ti,k2g-dss.example.dt.yaml
Documentation/devicetree/bindings/display/ti/ti,k2g-dss.example.dt.yaml: dss@02540000: 'ports' does not match any of the regexes: 'pinctrl-[0-9]+'
Documentation/devicetree/bindings/display/ti/ti,k2g-dss.example.dt.yaml: dss@02540000: 'port' is a required property

The ports definition in the yaml file does not looks like
what you have in the other yaml files.

The rest was fine - not other warnings in my build testing.

When you have the above warning fixed then I suggest you apply
the driver to drm-misc-next.
And then handle eventual updates in-tree.

If you lack commit-access I can commit the driver, but you should apply
for commit access theni, allowing you to maintain the driver in the future.

	Sam
