I wonder about the usage of the signal variable of struct v4l2_tuner. I have found only to use it to get the signal strength on drivers. The si470x radio device can set the seek threshold value of RSSI(Received Signal Strength Indicator) when the device scans the channels, so if the current RSSI value is low than the seek threshold value, the device decides the frequency is nonvalidate channel. So, i need v4l2 interface to set the best seek threshold value and i want to use the signal of struct v4l2_tuner for it. Can the signal variable be used to set the value?
