Subject: [PATCH] ath9k_hw: disable PLL / Clkreq for ASPM for AR9003
Date: Tue, 11 Jan 2011 17:46:31 -0800 [thread overview]
Message-ID: <1294796791-2521-1-git-send-email-lrodriguez@atheros.com> (raw)
This changes the PCIE PHY programming for better interoperability
with ASPM states. Without this AR9003 chipsets will hang when
using ASPM. This reproducible against an Apple Airport Extreme AP
by simply pinging it.
