22 | * These are data structures found in platform_device.dev.platform_data, | |
d254c8f7 | 23 | * and describing board-specific data needed by drivers. For example, |
73a59c1c SP |
24 | * which pin is used for a given GPIO role. |
25 | * | |
26 | * In 2.6, drivers should strongly avoid board-specific knowledge so | |
27 | * that supporting new boards normally won't require driver patches. | |
28 | * Most board-specific knowledge should be in arch/.../board-*.c files. | |
