- * CHARACTER DEVICE DISPATCHING
- *
- * All ieee1394 character device drivers share the same major number
- * (major 171). The 256 minor numbers are allocated to the various
- * task-specific interfaces (raw1394, video1394, dv1394, etc) in
- * blocks of 16.
- *
- * The core ieee1394.o module allocates the device number region
- * 171:0-255, the various drivers must then cdev_add() their cdev
- * objects to handle their respective sub-regions.
- *
- * Minor device number block allocations:
- *
- * Block 0 ( 0- 15) raw1394
- * Block 1 ( 16- 31) video1394
- * Block 2 ( 32- 47) dv1394
- *
- * Blocks 3-14 free for future allocation
- *
- * Block 15 (240-255) reserved for drivers under development, etc.
