Hi Paul,
just found that we don't have CONFIG_DRM_DISPLAY_CONNECTOR configured...
Maybe the v3 code simply works without *any* connector setup - like our hack.

Now, the connector driver is found and registered and of_drm_find_bridge()
no longer returns NULL. I.e. my patch according to Paul C's suggestion seems
to work better.

It still does not work because dw_hdmi_bridge_attach() is called with
flags = DRM_BRIDGE_ATTACH_NO_CONNECTOR... but that can be analysed by
some dump_stack();

BTW: it looks as if there is some code duplication for detecting
"ddc-i2c-bus" in dw-hdmi.c and in display-connector.c We have neither
one defined in our device trees and use the internal driver through
