There seems to always be some sort of contention about those being bridge drivers - I think I remember Thierry speaking up about that. But I don't remember if any different solution was suggested. Also as we have seen with current shared IPs (dw-hdmi + analogix-dp) there are always implementation-specific parts and deciding which needs to land where is difficult without the secondary user present. The first iterations where using a bridge-driver-base for it but I guess it was to much hassle without seeing another user on the horizon. > The drm/hisilicon IP seems to use a very similar DSI Designware IP (the > register offsets seems to be the same).

I guess, the second user now gets to do the generalization ;-) Heiko _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
