Can you explain what do you meant by can't be reused for pre-tegra210 or 
for tegra186/194?

support for other tegra's can be added to same tegra-video driver. 
tegra-video host1x driver can be updated to add other tegra's vi and csi 
compatibles to host1x subdevs and vi and csi driver can be updated to 
add other tegra soc data and need to add coresponding tegra186/194/xxx.c 
file with tegra specific prog sequence
