From 5323fe996b6a62be2201de2b2a5f6917a6040cb1 Mon Sep 17 00:00:00 2001
From: Michael Sevakis <jethead71@rockbox.org>
Date: Fri, 30 Nov 2007 05:16:56 +0000
Subject: Move encoder CPU boost control to the core. Allow CPU to sleep a bit
 when PCM buffer is empty and save some power. Codec API becomes incompatible
 so full updates! :)
