The omapdrm and omapdss drivers are architectured based on display pipelines made of multiple components handled from sink (display) to source (DSS output). This is incompatible with the DRM bridge and panel APIs that handle components from source to sink.
To reconcile the omapdrm and omapdss drivers with the DRM bridge and panel model, we need to reverse the direction of the DSS device operations. Start with the connect and disconnect operations.
