I would prefer the names to be just a bit more descriptive:
#define IPUV3_CHANNEL_MEM_VDI_PREV 8
#define IPUV3_CHANNEL_MEM_VDI_CUR 9
#define IPUV3_CHANNEL_MEM_VDI_NEXT 10
The reference manual states that the purposes of these channels are
"Previous field", "Current field", and "Next field" input to the VDIC,
respectively.
