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