It's my opinion that we have to be careful in trying to be too

ever hope to be able to do that.

An opinion has been expressed, that my proposed API was too complex, that, 
for example, the .packing parameter was not needed. Just to give an 
argument, why it is indeed needed, OMAP 3 can pack raw 10, 12, (and 14?) 
bit data in two ways in RAM, so, a sensor would use the .packing parameter 
to specify how its data has to be arranged in RAM to produce a specific 
fourcc code.
