V1:
This series tidies up the code to get/set/clear discovered firmware feature
bits and adds a new debugfs entry to read the feature bits as strings.

This is a handy way of debugging WiFi on different platforms without
necessarily having to recompile to see the debug printout on firmware boot.

Bryan O'Donoghue (4):
  wcn36xx: Rename clunky firmware feature bit enum
  wcn36xx: Move firmware feature bit storage to dedicated firmware.c
    file
  wcn36xx: Move capability bitmap to string translation function to
    firmware.c
  wcn36xx: Add debugfs entry to read firmware feature strings
