From 4921be8058f1c8854e501305b96196856fe7f830 Mon Sep 17 00:00:00 2001 From: Sujith Date: Fri, 18 Sep 2009 15:04:27 +0530 Subject: ath9k: Fix RTC reset for AR5416 For AR5416 chipsets, clearing RTC_RESET_EN when setting the chip to SLEEP mode results in high power consumption. This patch fixes this issue by not clearing it for AR5416. Signed-off-by: Sujith Signed-off-by: John W.
