* radio channel. The properties are passed via

* struct @analog_params;.
|

* @has_signal: returns 0xffff if has signal, or 0 if it doesn't.
|
||||
* @get_afc: Used only by analog TV core. Reports the frequency
|
||||
* drift due to AFC.
|
||||
* @tuner_status: callback function that returns tuner status bits, e. g.
|
||||
* TUNER_STATUS_LOCKED and TUNER_STATUS_STEREO.
|
||||
* @standby: set the tuner to standby mode.
|
||||
* @release: callback function called when frontend is dettached.
|

* drivers should free any allocated memory.
|
||||
* @i2c_gate_ctrl: controls the I2C gate. Newer drivers should use I2C
|
||||
* mux support instead.
|
||||
* @set_config: callback function used to send some tuner-specific
|

* parameters.
