>Description:
The HAL Merlin fast clock check simply checks the EEPROM flag.

The ath9k check is (hw.c):

               if (AR_SREV_9280_20(ah) &&
                    ((ah->eep_ops->get_eeprom(ah, EEP_MINOR_REV) <=
                      AR5416_EEP_MINOR_VER_16) ||
                     ah->eep_ops->get_eeprom(ah, EEP_FSTCLK_5G)))
                        pCap->hw_caps |= ATH9K_HW_CAP_FASTCLOCK;

Go through the code, add a capability flag for fastclock, use that instead of the #define, and make sure that capability is properly set at Merlin probe/attach time.
