From c0ad4fac5011c5534c45011ee8dee2b3de256663 Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Tue, 31 May 2011 11:27:01 +0300 Subject: [PATCH] omap: rx51: Don't power up speaker amplifier at bootup Speaker amplifier is accidentally powered up in early TWL gpio setup. This causes a few mA of needless battery current consumption. Without this patch the amplifier can be shutdown only by having one active audio playback and shutdown cycle to speaker output. Thanks to Kalle Jokiniemi for noticing the issue.
