Subject: [PATCH 27/75] ath9k_hw: Enable manual peak calibration for AR9485

3.8.13.2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sujith Manoharan <c_manoha@....qualcomm.com>

commit e99c60b58b595eaa1c279922ae29d5397c787294 upstream.

Manual peak calibration is currently enabled only for
AR9462 and AR9565. This is also required for AR9485.
The initvals are also modified to disable HW peak calibration.
