  *			V4L2_TUNER_ANALOG_TV and/or V4L2_TUNER_DIGITAL_TV,
  *			describing if the tuner should be used to support
  *			Radio, analog TV and/or digital TV.

  *			Only a very few tuners require it and its usage on
  *			newer tuners should be avoided.
  * @tuner_callback:	Some tuners require to call back the bridge driver,

  *			bridge chipset, in order to do things like resetting
  *			the device.

  * Older boards only had a single tuner device. Nowadays multiple tuner

  *
  * Since multiple devices may be present it is no longer sufficient to
  * send a command to a single i2c device. Instead you should broadcast
  * the command to all i2c devices.
  *
  * By setting the mode_mask correctly you can select which commands are
  * accepted by a specific tuner device. For example, set mode_mask to
  * T_RADIO if the device is a radio-only tuner. That specific tuner will
  * only accept commands when the tuner is in radio mode and ignore them
  * when the tuner is set to TV mode.

	* @addr: I2C address used to control the tuner device/chipset
	* @type: Type of the tuner, as defined at the TUNER_* macros.
	* Each different tuner model should have an unique
	* identifier.
	* @mode_mask: Mask with the allowed tuner modes: V4L2_TUNER_RADIO,
	* V4L2_TUNER_ANALOG_TV and/or V4L2_TUNER_DIGITAL_TV,
	* describing if the tuner should be used to support
	* Radio, analog TV and/or digital TV.
	* @config: Used to send tuner-specific configuration for complex
	* tuners that require extra parameters to be set.
	* Only a very few tuners require it and its usage on
	* newer tuners should be avoided.
	* @tuner_callback: Some tuners require to call back the bridge driver,
	* in order to do some tasks like rising a GPIO at the
	* bridge chipset, in order to do things like resetting
	* the device.
	*
	* Older boards only had a single tuner device. Nowadays multiple tuner
	* devices may be present on a single board. Using TUNER_SET_TYPE_ADDR
	* to pass the tuner_setup structure it is possible to setup each tuner
	* device in turn.
	*
	* Since multiple devices may be present it is no longer sufficient to
	* send a command to a single i2c device. Instead you should broadcast
	* the command to all i2c devices.
	*
	* By setting the mode_mask correctly you can select which commands are
	* accepted by a specific tuner device. For example, set mode_mask to
	* T_RADIO if the device is a radio-only tuner. That specific tuner will
	* only accept commands when the tuner is in radio mode and ignore them
	* when the tuner is set to TV mode.
