| 8 | * - Added support for a separate Radio tuner |
| 9 | * - Major rework and cleanups at the code |
| 10 | * |
| 11 | * This driver supports many devices and the idea is to let the driver |
| 12 | * detect which device is present. So rather than listing all supported |
| 13 | * devices here, we pretend to support a single, fake device type that will |
| 14 | * handle both radio and analog TV tuning. |
