Could you maybe also bring over functionality for real bridge-handling?
That way we'd have support for things like the dp-connector bridge.
In the 6.1 vendor-tree I've found commits
94e598190128 ("drm/rockchip: analogix_dp: Add support for external bridge")
437e0a901b14 ("drm/bridge: analogix_dp: Support split mode for bridge chain")
needing a bit of cleanup of course, but that would get rid of the driver
not handling the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag too.
With a bit of streamlining, we could maybe even get rid of the panel-part
completely, similar to how the dw-dsi controllers do it [0]
Thanks

devm_drm_of_get_bridge() combines drm_of_find_panel_or_bridge()
with devm_drm_panel_bridge_add(), so indepent of it being either a
panel or other bridge, the driver below only needs to handle bridges.
