From c96f7f537d0fcc0f94a6c799ec9f294aa0d0b798 Mon Sep 17 00:00:00 2001 From: Juha Yrjola Date: Thu, 21 Sep 2006 18:25:42 +0300 Subject: [PATCH] ARM: OMAP2: Keep both APLLs active during bootup Enabling and disabling the 54 MHz and 96 MHz APLLs can happen unnecessarily often during bootup. Make sure they're kept enabled during init.
