I can recommend linux/Documentation/i2c/writing-clients.

Basically you can add I2C_CLASS_TV_ANALOG to
av7110->i2c_adap.class (av7110.c) and load
the msp3400 driver, it should automatically
attach to the bus. This is of course just a hack,
because the classes were introduced specifically
to keep analog stuff away from DVB I2C busses,
because it causes problems in some cases.
