Adds the VDIC field input IDMAC channels. These channels
transfer fields F(n-1), F(n), and F(N+1) from memory to
the VDIC (channels 8, 9, 10 respectively).

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.

right. Ok I will make that change in next version.
