Hi
The hybrid tuner FMD1216MEX_MK3 after cold start has disabled IF.
This tuner has internal I2C switch. This switch switch I2C bus between DVB-T and IF part.
Default state is DVB-T. When module saa7134 is load it can't find IF tda9887 and disable
analog TV mode.
This patch set internal I2C switch of the tuner to IF by send special value to the tuner as for receive
analog TV from low band. It can be usefule for other cards.
I didn't set configure a tuner by a tuner model because this tuner can has different I2C address.
May be we can do it later after discuss for more robust support a tuners.
