Patch is:
Signed-off-by: Sam Ravnborg <sam at ravnborg.org>

please consider a few follow-up patches:
1) Replace deprecated drm_bridge_funcs with the _atomic_ variants.
2) Replace the deprecated drm_bridge_chain_pre_enable() with the atomic
   variant.
3) Use pr_() and dev_() logging in favour of DRM_ logging.
   DRM_ logging is deprecated these days and do not belong in bridge
   drivers anyway.

Maxime has a few patches pending for this driver - it would be great if
you could look them up and review them.
Maybe you can get some review in feedback.
