Subject: [PATCH 2/6] ath9k: Bypass EEPROM for diversity cap for AR9565
Date: Mon, 2 Sep 2013 11:14:01 +0530 [thread overview]
Message-ID: <1378100645-29868-2-git-send-email-sujith@msujith.org> (raw)
In-Reply-To: <1378100645-29868-1-git-send-email-sujith@msujith.org>
From: Sujith Manoharan <c_manoha@qca.qualcomm.com>
Use a default antenna diversity value for AR9565 instead
of relying on the EEPROM/OTP programmed value.
