Hi Bill,
I recommend reading Documents/video4linux/v4l2-framework.txt. It's not clear
from your question whether you want an example driver for an i2c device, or
an example for how to use i2c devices in an PCI or USB driver.
A simple, but decent example source for the first would be wm8739.c and for
the second we have saa7134 or cx18.
It's a bit in flux at the moment since we are moving all drivers over to the
v4l2_device/v4l2_subdev structure, but some still use the old model.
Regards,
Hans
