Subject: [PATCH 01/11] ath9k_hw: Fix a reset failure on AR9382 (2x2).
Date: Wed, 10 Nov 2010 05:03:06 -0800 [thread overview]
Message-ID: <1289394196-3465-1-git-send-email-vasanth@atheros.com> (raw)
From: Senthil Balasubramanian <senthilkumar@atheros.com>
AR9382 needs to be configured for the correct chain mask before
running AGC/TxIQ caliberation. Otherwise reset would fail.
