These two patches are needed to make tc358767 work in the
DRM_BRIDGE_ATTACH_NO_CONNECTOR case, at least when using a DP connector.
The first patch, "drm/bridge: tc358767: Support input format negotiation
hook" was already sent separately, but I included it here for
completeness, as both are needed to get a working display.

I have tested this with TI AM654 EVM with a tc358767 add-on card.

What's the plan for these fixes? I'm not yet seeing them in Linus' tree,
thus also not in stable.

The discussion continued in v2 of the series. There are some open 
question in the tc358767 behavior.
