-/* 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.

+ * struct tuner_setup - setup the tuner chipsets
+ *
+ * @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.
