Subject: [PATCH 3.1] ath9k_hw: fix calibration on 5 ghz
Date: Mon, 29 Aug 2011 10:06:14 +0200 [thread overview]
Message-ID: <1314605174-66206-1-git-send-email-nbd@openwrt.org> (raw)
ADC calibrations cannot run on 5 GHz with fast clock enabled. They
need to be disabled, otherwise they'll hang and IQ mismatch calibration
will not be run either.
