New Revision: 218420
URL: http://svn.freebsd.org/changeset/base/218420

Log:
  Add in some AR9280 specific board configuration options.
  
  * The existing radio config code was for the AR5416/AR9160 and missed out
    on some of the AR9280 specific stuff. Include said stuff from ath9k.
  
  * Refactor out the gain control settings into a new function, again pilfered
    from ath9k.
  
  * Use the analog register RMW macro when touching analog registers.
  
  Obtained from:	Linux ath9k
