22 * These are data structures found in platform_device.dev.platform_data,
23 * and describing board-specific data needed by drivers. For example,
24 * which pin is used for a given GPIO role.
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.
