After some tedious work with a logic probe and a magnifying glass, I've determined that GPIO 7 is used to switch between the DTT7612's Sound 4.5 MHz IF output on pin 12 and the FM 10.7MHz If output on pin 11. GPIO 2 is used to switch the card's analog sound output from from the analog input connector to the CX23883's audio DACs. So, in radio mode GPIO2 = 1 and GPIO7 = 0. Add some comments about how the HD-3000's GPIOs are connected. Delete the vmux setting for the radio, as vmux doesn't apply to radio mode. Also delete the lines setting unused gpio words to zero; it's not necessary as 0 is the default value for uninitialized fields.
