From 9a658d2b5c222b62919ab47b11c907c731ac180a Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Mon, 21 Jun 2010 18:38:47 -0400 Subject: ath9k_hw: fix ASPM setting for AR9003 The AR_WA register should not be read when in sleep state so add a variable we can stash its value into for when we need to set it. Additionally the AR_WA_D3_TO_L1_DISABLE_REAL (bit 16) needs to be removed. Cc: Aeolus Yang Cc: Madhan Jaganathan signed-off-by: Luis R. Rodriguez Signed-off-by: John W.
