   4 Subject: [PATCH] rt2x00: Export all register stats through debugfs
   5
   6 By exporting the register base, and word size to userspace
   7 through debugfs it will be easier to create scripts which
   8 parse the register information. This makes debugging and
   9 register dumps information easier.
  10 This will unfortunately not be backward compatible with
  11 the previous approach, but that is not important in this case
  12 since manually fixing the layout of the dumpfile to match the
  13 new style then interpreting the data without a script.
  14
  15 Also be more consistent with using tabs to seperate different
  16 fields.
