The videobuf2 supports 3 types of buffer:
1: VIDEOBUF2_DMA_CONTIG
2: VIDEOBUF2_DMA_SG
3: VIDEOBUF2_VMALLOC

It all depends on your hardware (bridge driver) which supports this
So if your bridge driver supports say VIDEOBUF2_VMALLOC then
in your Kconfig for the bridge driver you need to add the following line
select VIDEOBUF2_VMALLOC so this will be built along your driver.

Hope this helps!
