Subject: ath9k: Enable PLL fix only for AR9340/AR9330
From: Sujith Manoharan <c_manoha@xxxxxxxxxxxxxxxx>
commit 19c361608ce3e73f352e323262f7e0a8264be3af upstream.
The PLL hang workaround is required only for AR9330 and
AR9340. This issue was first observed on an AP121 and the WAR
is enabled for AR9340 also (DB120 etc.), since it uses a PLL
design identical to AR9330. This is not required for AR9485 and AR9550.
Various bugs have been reported regarding this:
