Yep. No succesful tuning at the moment. There might also be an issue
with the reset signal and writing to GPIOCTR, as the module at the
moment loads succesfully only once.
As far as I can make out, the LNB power control is probably GPIO 16 and
17, not sure which is which, and how they work.
GPIO15 is wired to tuner #reset
New patch to test

A little tweaking produced the required voltages for the LNB:
switch (voltage) {
case SEC_VOLTAGE_18:
dm1105_gpio_set(dev, GPIO16 | GPIO17);
break;
case SEC_VOLTAGE_13:
dm1105_gpio_andor(dev, GPIO16 | GPIO17, GPIO17);
break;
default:
dm1105_gpio_clear(dev, GPIO16 | GPIO17);
break;
}
But unfortunately tuning is still failing. Could it be an issue with the
21xx driver? I will read up on the Si2109.
