61/* Offsets to the device registers.
62 Unlike software-only systems, device drivers interact with complex hardware.
63 It's not useful to define symbolic names for every register bit in the
64 device. The name can only partially document the semantics and make
65 the driver longer and more difficult to read.
66 In general, only the important configuration values or bits changed
67 multiple times should be defined symbolically.
