Hi,

This patchset rework the ingenic-drm driver, improving the code in
various places.

The most important change is the last patch, which updates the
ingenic-drm driver to use a top-level bridge per output, making use of
the bus format and flag negociation implemented in the bridge code. All
the external bridges are now attached with
DRM_BRIDGE_ATTACH_NO_CONNECTOR.

Cheers,
-Paul
