As Amitay has said, the GPIO is an elusive thing. Steve posted
previously that the XC2028 sample code is similar to what should be
used to bring the tda10048 out of reset, but I can't seem to obtain any
useful data from the windows driver.
These are the only addresses I can see, but I've no idea how to obtain GPIO's from this.
HKR, "I2C Devices", "Device 0, Data1",0x00010001,0x03 ; Tuner ID
HKR, "I2C Devices", "Device 0, Data2",0x00010001,0xC0 ; Tuner slave addr.
HKR, "I2C Devices", "Device 0, Data3",0x00010001,0x86 ; Tuner IF PLL slave addr.
With
debug options i2c_scan=,1gpio_tracking=1, irq_debug=1, this is my
dmesg. Perhaps something in here may mean something to the more
experienced members of this list ...

0x10 >> 1 is the tda10048 then.
