From 4a677ac5d0a4fad286cdfb4890a5e2de61534b1c Mon Sep 17 00:00:00 2001 From: Liam Girdwood Date: Fri, 5 Aug 2005 10:24:36 +0200 Subject: [PATCH] [ALSA] PXA27x AC97 warm reset ARM PXA2XX driver This patch extends the period of an AC97 warm reset on the PXA27x from 50uS to 500uS. The shorter reset didn't always guarantee that the codec would wake up. Changes:- o Change pxa27x warm reset period to 500uS o Removed double semi-colon.
