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