12 * bktr_core : This deals with the Bt848/849/878/879 PCI Frame Grabber,
13 *               Handles all the open, close, ioctl and read userland calls.
14 *               Sets the Bt848 registers and generates RISC pograms.
15 *               Controls the i2c bus and GPIO interface.
16 *               Contains the interface to the kernel.
17 *               (eg probe/attach and open/close/ioctl)
