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.
