I retested my device and tried several different GPIO sequences but so far every time I change between the Analog and digital interface, the SAA7113 needs to be reinitialized.  I tried leaving both the digital and analog interfaces enabled by setting the GPIO to 7c but then the LG demod does not initialize.  

Either way it looks like I will have to reinitialize the device after switching between interfaces.  

Other than that do you want me to remove the suspend GPIO?  Since I don't have the equipment to measure the power, I don't know for a fact if the device really has been put in a suspend state or not.  

Thanks,
