From 653fe371226fcbcc41b4662d35d2207648a6075d Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Mon, 21 Jun 2010 18:38:48 -0400 Subject: [PATCH] ath9k_hw: move LowPower array writes to ar9003_hw_configpcipowersave() The LowPower array writes disables the PLL when ASPM is enabled. The host driver makes quite a few calls to ath9k_hw_configpcipowersave() and these same calls also need to ensure the PLL is off when they issue it.
