Well, the naming of macros is debatable as Jonathan pointed out[1] and
the unusual/odd naming pointed to you was for rotation registers

#define ADIS16209_ROT_OUT_REG		0x10

I renamed the unusual/odd naming macros for eg
#define ADIS16209_DIAG_STAT_FLASH_UPT_BIT

to

#define ADIS16201_DIAG_STAT_FLASH_UPT_FAIL_BIT

as it didn't look like a failure bit address for which I consulted Jonathan to which
he agreed. Also, *DIAG_STAT* seems like a good name since these status registers
are serving the purpose of diagnosing the device behavior. Again, GLOB_CMD stands
for Global Command register for controlling the deivce operation such as
Fatory Reset, Software Reset, etc.

See, it is difficult to point the perfect names than the suitable ones!
And let's just leave these *bikeshedding* ;-)
