Hi Fabrizio, (CC'ing Sam) Thank you for the patch.

Please, no. We already have too many connector types for panels, when userspace should really not care. DRM_MODE_CONNECTOR_LVDS, DRM_MODE_CONNECTOR_eDP, DRM_MODE_CONNECTOR_DSI, DRM_MODE_CONNECTOR_DPI and probably DRM_MODE_CONNECTOR_SPI should have been DRM_MODE_CONNECTOR_PANEL. This has been discussed in [1]. Let's instead define a DRM_MODE_CONNECTOR_PANEL, possibly as an alias to one of the existing types, and deprecate the other types.
