While Dmitry helped a lot with looking at bridge drivers recently,
I think your recipient list does miss a number of other people
listed as bridge reviewers/maintainers.

$ scripts/get_maintainer.pl drivers/gpu/drm/bridge
Andrzej Hajda <andrzej.hajda@...el.com> (maintainer:DRM DRIVERS FOR BRIDGE CHIPS)
Neil Armstrong <neil.armstrong@...aro.org> (maintainer:DRM DRIVERS FOR BRIDGE CHIPS)
Robert Foss <rfoss@...nel.org> (maintainer:DRM DRIVERS FOR BRIDGE CHIPS)
Laurent Pinchart <Laurent.pinchart@...asonboard.com> (reviewer:DRM DRIVERS FOR BRIDGE CHIPS)
Jonas Karlman <jonas@...boo.se> (reviewer:DRM DRIVERS FOR BRIDGE CHIPS)
Jernej Skrabec <jernej.skrabec@...il.com> (reviewer:DRM DRIVERS FOR BRIDGE CHIPS)

As you'll need to do a v2 for the binding, please add the missing people
to the recipients.


For the change itself, can you improve the commit message a bit.

I assume the Single/Dual/Quad-Pixel config is a real hardware-feature
that is set when the IP is integrated into the soc? Or this a runtime
setting and a soc can support multiple output variants?


Thanks
Heiko
