| 184 | * |
| 185 | * @addr: I2C address used to control the tuner device/chipset |
| 186 | * @type: Type of the tuner, as defined at the TUNER_* macros. |
| 187 | * Each different tuner model should have an unique |
| 188 | * identifier. |
| 189 | * @mode_mask: Mask with the allowed tuner modes: V4L2_TUNER_RADIO, |
| 190 | * V4L2_TUNER_ANALOG_TV and/or V4L2_TUNER_DIGITAL_TV, |
| 191 | * describing if the tuner should be used to support |
| 192 | * Radio, analog TV and/or digital TV. |
| 193 | * @config: Used to send tuner-specific configuration for complex |
| 194 | * tuners that require extra parameters to be set. |
| 195 | * Only a very few tuners require it and its usage on |
| 196 | * newer tuners should be avoided. |
| 197 | * @tuner_callback: Some tuners require to call back the bridge driver, |
| 198 | * in order to do some tasks like rising a GPIO at the |
| 199 | * bridge chipset, in order to do things like resetting |
| 200 | * the device. |
| 201 | * |
| 202 | * Older boards only had a single tuner device. Nowadays multiple tuner |
| 203 | * devices may be present on a single board. Using TUNER_SET_TYPE_ADDR |
| 204 | * to pass the tuner_setup structure it is possible to setup each tuner |
| 205 | * device in turn. |
| 206 | * |
| 207 | * Since multiple devices may be present it is no longer sufficient to |
| 208 | * send a command to a single i2c device. Instead you should broadcast |
| 209 | * the command to all i2c devices. |
| 210 | * |
| 211 | * By setting the mode_mask correctly you can select which commands are |
| 212 | * accepted by a specific tuner device. For example, set mode_mask to |
| 213 | * T_RADIO if the device is a radio-only tuner. That specific tuner will |
| 214 | * only accept commands when the tuner is in radio mode and ignore them |
| 215 | * when the tuner is set to TV mode. |
