From 0e4660cbe51276e86dbdab17228733dbcdb49249 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Mon, 29 Aug 2011 10:06:14 +0200 Subject: [PATCH] ath9k_hw: fix calibration on 5 ghz 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.
