I have been working on the driver over the past days and been making some progress. Right now I am stuck with a small problem that I have no idea how to deal with. It seems that the fc0012 tuner supports V-Band and U-Band. To switch between those modes a GPIO output value needs to be changed. In the original Realtek driver this is done at the beginning of the set_parameters callback. Is there a different callback that can be used for this or is it ok to write a RTL2832u register from the demodulator code?
Aah, I suspect it is antenna switch or LNA GPIO. You don't say what is meaning of that GPIO... If it is FC0012 input, which I think it is not, then you should use FE callback (named as callback too) with DVB_FRONTEND_COMPONENT_TUNER param. But I suspect it is not issue.
So lets introduce another solution. It is fe_ioctl_override. Use it. You will find good examples both cases using following GIT greps git grep fe_ioctl_override drivers/media git grep FRONTEND_COMPONENT Antti -- http://palosaari.fi/ -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
