Subject: [PATCH 18/26] ath9k_hw: Read and configure turnning caps to regulate freq accuracy
Date: Tue, 30 Nov 2010 23:32:47 -0800	[thread overview]
Message-ID: <1291188775-13707-19-git-send-email-vasanth@atheros.com> (raw)
In-Reply-To: <1291188775-13707-1-git-send-email-vasanth@atheros.com>

Right now it is done for only AR9485, will be done for ar9003 also
after proper testing.
