From 49e03402327ab69a26f604398982ef14123900a2 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Fri, 11 Oct 2013 19:15:38 +0300 Subject: ARM: OMAP3: control: add API for setting IVA bootmode OMAP3 PM core requires IVA2 bootmode to be set to idle during init. Currently, a direct register write is used for this. Add a new ctrl API for this purpose instead.
