This patch series adds support for this feature to the ti-sn65dsi86 driver. The series starts with miscellaneous fixes and improvements in patch 01/11 to 04/11. Patch 05/11 then moves to the panel-bridge helper, and is followed by patches 06/11 and 07/11 that refactor the code to prepare for the next steps. As my goal is to use the sn65dsi86 with the R-Car DU driver, which requires DRM_BRIDGE_ATTACH_NO_CONNECTOR support, the series continues with support for this feature. In patch 08/11 the bridge connector operations are added, and in 09/11 the connector creation is made optional. Patch 10/11 then implements supports for DisplayPort mode, enabled automatically when the next component in the pipeline isn't a panel. Finally, patch 11/11 adds hotplug detection support, which isn't very useful for eDP, but is needed for DisplayPort. This series is an RFC as I haven't been able to test it fully yet. The platform I'm working on is missing support for three other components in the display pipeline (I'm on it), which are required in order to run tests. I would however like to receive feedback on the approach already, in case problems would need to be solved.
