     The iic character device driver provides generic i/o to any iicbus(4)
     instance.  In order to control I2C devices, use /dev/iic? with the
     following ioctls:

     Ioctl         Description
     I2CSTART      send start condition to the specified device (with 7-bit
                   address) on the bus
     I2CSTOP       send stop condition to the bus
     I2CRSTCARD    reset the bus

     You may also use read/write routines, then I2C start/stop handshake is
     managed by the iicbus system.
