We are moving to a model where the display driver have the
responsibility to create the connector - not the bridge.

The flags argument to:

    drm_bridge_attach(encoder, bridge, previous, flags);

is used to tell if the brigde shall create the connector or the display
driver does it - DRM_BRIDGE_ATTACH_NO_CONNECTOR.

It would be preferred that we moved the relevant bridge drivers to the
new model no so you did not need to support the old model in the driver.

If you help identify the bridge drivers we could migrate them to the new
model and you could help testing?

What bridge drivers will be used for tegra?
